I agree with Iceheart - the old Spyro games for PS1. Those were beautiful games. Too bad Activision is making a (seemingly) terrible game that'll probably ruin the series forever.
Anyhow, I have one game. My favourite game ever (so far). It's for the DS. And it's called,
GHOST TRICK: PHANTOM DETECTIVE
Ohmygosh it's beautiful, too. I cried at the ending! It's sad. It's from Capcom, yeah. There are animals in it, a dumb Pomeranian that I personally hate but everyone loves called Missile.
BUT ohmygosh it's a wonderful game, with 18 chapters of awesoooooooooomeness. It's a puzzle...ish game. Anyways, here is the Wikipedia link for the game:

I reccomend this game 10/10. You should totally play it.
