SonAmy evidence!!!!!!!!!!!!!!:

This is gonna take a while to type....

-Sonic CD:
Amy got captured, and Sonic saved her (BTW, This is the first time that they ever met)... and after that, she started following him around and chasing after him...... STALKER ALERT! (lol)

-Sonic Rush
Amy becomes jealous when Blaze wants to see Sonic, but it turns out that Blaze likes Silver, not Sonic.

-Sonic heroes
Amy's main goal is to chase after Sonic.

-Sonic chronicles: The dark brotherhood
Okay, I have this game, and it's SUPER fun, but very hard. The thing to make up for that is: You get to choose what Sonic says. When you first see Amy, she'll say "Hey, Sonic! I'm glad to see you, but.... not that glad. I have a boy friend, now." In one of Sonic's answers, it has a flare of jealousy embedded into it. Another time in the game, when Rouge tries to flirt with Sonic, Amy gets jealous and starts to say "Hey! You can't talk that way to him!" Rouge says "How come? You already have a boy friend, remember?" You now have the choice to stand up for Amy, by telling Rouge to lay off and leave her alone. (That's what I did!). Later on, if you're super nice to Amy, she'll admit "Dexter isn't real... I was just trying to make you jealous." In another part in Chapter 10 before the battle, Amy will ask Sonic "Do you care about me?" One of Sonic's responses went like this "Well of course I care about you, Amy!" BE NICE!!!!!!!!!!!!!!! And at the end of the game.... this really surprised me....... Sonic and Amy were close to kissing point! And after that, Amy will ask Sonic if he would want to go out with her sometime. And the best answer to that would be "Sure."

-Sonic riders
I have this game, so I know the following:
Amy surprises Sonic by entering the competition. But what made him say "Darn!" in the middle of the game was when Eggman pulled unconscious Amy out of a bush and said " Look before you move." He threatened "Now hand over the chaos emeralds before she gets hurt." Now... Sonic has a serious problem with doing something before thinking about it, so he springs into action and catches Eggman (and Amy) into an attack that made them fly away (sounds weird? You're right.). When Sonic, Tails and Knuckles were walking on, a mad voice came into ear shot. "Soooonic!" He turns around to see her standing there. "Amy?" He says."How could you dive into Eggman knowing I was there?!" She snaps at him, looking down. Sonic gets nervous, replying "Well, Amy... I thought it would be okay.... with you, and um....." She looks up, very furious. Sonic seems very scared by this, and starts running away. Apparently, Amy won't give up without a fight. She takes out her hammer and starts chasing him around with it. "SONIC! I won't forgive you this time!" Amy screams, trying to hit him. But eventually, she does forgive him :).

-Sonic riders: Zero gravity (Sequel to "Sonic riders")
Something grabs Sonic from behind, and covers his eyes. "Guess who?" A voice asks. "Amy?" She uncovers his eyes. "What are you doing here?" "Faded lovers are always together, silly." She replies, winking. Sonic seems to be embarrassed by this. "Aaaaamy!" He moans. "Alright, you caught me. I was running away from those robots. I was so scared!" Amy hugs him. At another part in the game, Sonic, Amy, Tails and Knuckles are at a hide out. An alarm erupts, then robots zoom by, apparently trying to run them over. "Look out!" Sonic screams, pushing Amy out of the way. The robots then explode before them. If you look real closely, you can see that Sonic is putting his hand in front of Amy. If you don't think that means anything, you're wrong! It means that he is trying to protect her. Jet appears before them. "Okay, girl! Hand over the ark of the cosmos, NOW!" He yells at Amy. "What are you talking about?" She asks. "Don't play dumb with me, girl! We know you took the Ark of the cosmos right out of our hands!" Jet accuses her. If you look at Sonic's facial expression, you can tell he's not happy. "Hey! Hold up a minute! Girls hate guys who rush them, Jet." He interrupts.

-Sonic '06
There's a stage in this game called the love test. You can choose between Amy or Elise to see which one Sonic loves. It can't be Elise cause there was a time paradox, causing them to never meet. And besides, when you choose Amy, it says "Ah. I understand that Amy is the one you choose. She is your long time love." Everyone hates Elise, anyways. And when Sonic was about to get killed by Silver, Amy came in the way of it, and Silver ended up not firing, giving Sonic a chance to escape. "Thanks, Amy." He says before leaving. "Leave it to me." She answers. And pretty much after that, there's a tiny SilvAmy moment (Not a very good couple), but she does mention "If I have to choose between the whole world and Sonic, then I'd pick Sonic!"

-Sonic Unleashed
Amy: Now I got you, Sonic!
*She tackles him, not realizing that he's in werehog form*
Sonic: Hey, let me go!
Amy: You're crazy if you think you can get away from Amy Rose, and....
*She looks up at him*
Amy: Hey.... who are you?!
Sonic:Uh............
*She pushed him away*

Amy: Oh my gosh! I am SOOOO Sorry! That was so strange.... I could of sworn it was him! Oh well.... see you later!

*She runs away, waving*

*Sonic holds out a hand... or paw?*

Chip: Well that was weird! How come that girl didn't know you were you, Sonic?

After that, Sonic is really disappointed, and the Sonic Team said that he was depressed because Amy didn't know it was him.

In another part of the game:

There are a lot of people, slowly dancing around like they were drunk or something :D.... One dude was holding onto Amy, spinning her around in circles.

Amy: HEY! What's the big idea???

Dude: Come on, babe! Let's dance the night away!

(My friend: Um, doesn't anyone realize that the 'babe' he was talking about is just a hedgehog?)

Amy: Let me go! HEELLLLLP!

Then, Sonic and Chip see it.

Chip: Hey, is some kind of party going on?

Sonic: No.... this isn't right.

Chip takes out a camera and takes a picture of it. A bunch of monsters rise up out of the people, and Amy passes out.

(My friend: Oh! That's creepy!)

Chip: It's a carnival of creeps out there!

And then, Sonic fights the monsters.

After the battle, Sonic (Still in werehog form) picks up Amy by the waist, helping her stand up. She wakes up, turning around. He looks away, afraid of what Amy would think of him now that he was.... well, a monster. Sonic quickly runs away from her. But...... she eventually finds oout the truth. Amy doesn't care about appearance, and Sonic should know that by now.

Sonic DX:

Flirtatious events.

-Sonic and the black knight

In the very beginning of the game, it is shown that Sonic was walking, carrying TWO chillidogs. It's possible that the other one was for someone else.....
Anyways, this is what happened when Sonic and the sword went to see "The lady of the lake":
"Hello, brave knight." Amy appears before them. "AHHHHHHHHHHHHHHH!" Sonic screams, then starts to run away. "Fool, where are you going?!" The sword asks. "But that's-" "You're being rude to the lady of the lake!" The sword snaps. Sonic comes back. "Bow your head before her." The sword says, and Sonic does it. "You're here because of Excaliber, aren't you?" Amy asks. "You don't waste your time, lady!" Sonic replies, putting his arm around her. "Ahem!" The sword says. Sonic sweatdrops, then pulls his arm away.
At the very end of the game, right after the credits, this happens:
You don't see anyone in particular, you can only hear talking...
Sonic: "And so, that's what happened."
Amy: "Aren't you forgeting something?"
Sonic: "What? The adventure and suspense on the wire?"
Amy: "That's really the lamest excuse ever! You just forgot about our date!"
Sonic: "But it's the truth, I tell ya! WAIT! Amy, PUT DOWN THAT HAMMER!!!"
Amy: "You get back here, Sonic.... SOOOOOOOOOOOOOOONNNIC!!!!!!!!!!!!!!!!!!!"
So..... the whole thing was just Sonic telling up the story of why he missed his and Amy's date.... that's funny!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sonic X:

Their relationship develops even further, turning them more into Girl friend and Boy friend.

Last but not least, an article in a March, 2005 issue of "Disney adventures", there's this thing called "The top 10 gaming mysteries of all time". Under the 'solved' category, question #10 states "Why doesn't Sonic confess his love for Amy Rose?" Notice that it's not like "Does Sonic like Amy?" because we already know that he loves her.

What it says:

To get an answer to this pressing question, we went staight to the Sonic Team headquarters:

"Although Sonic is clearly interested in her, Sonic has always been too shy to declare his true feelings."

Shy? Could have fooled us!

And.... in one game where it's introducing the characters, it descibes Amy Rose as "Sonic's go-happy love interest!".
