When I was a kid and got my first game system, the original sony playstation, my favorite game was Spyro The Dragon. I loved every game in the series (Save 'Year of the Dragon Fly', mostly due to the crappy graphics), up until 'A New Beginning.' The fact that they were now going with a linear story plot instead of letting the player do their own thing at their own pace pissed me off. They took away the "for fun" mini-games, only let you fly once in the entire game, and that whole having to gather the little orbs to breath fire, lightning, etc. pissed me off more than anything. I have not been able to bring myself to play any of the games since, not wanting to see the game that got me into video games in the first place butchered any further.
I think I could consider myself one of the many Kingdom Hearts fan-girls. It was the first game I got when I recieved my PS2, and I've also played KH: COM and KH2. I love the story and the game play, though I think it could do with less of those "Press this now for super awesome attack" things in the boss battles.
