I know... 0.0 Seen the Boom series, right? Sonic seems to like Amy more...well, in the mainstream/modern one he prefers her as a friend, but watching the Boom series kinda makes me feel he's more than a friend... 0.0
Well, I think they make the two more likely to feel something for one another in the animated shows; while in the games Amy feels something for Sonic, but Sonic just likes her as a friend (like you said)
