N64: The Legend of Zelda: Ocarina of time - this game got so much right back then that wasn't really tried or didn't properly work out up until that point; fluently controlling your character around 3D environments, awesome areas; great dungeon designs and a ton of sidequests will keep you busy for some time.
GCN: Super Smash Bros. Melee - the game that got me into SSB and fighters in general. It's combat was fast but the controls were always spot on; if you lost, you were the one to blame; also one of my first GCN games, so I hold it closesly to my heart because of nostalgia. (I guess I actually would've gone for Wind Waker, but I like to vary things a little)
Wii: Super Mario Galaxy - great platforming, supreme music (really, some of the best I've heard from a video game) it has a certain appeal/charme to it which I can't quite describe. Let's call it 'Nintendo magic' (don't hate me to the ground pls :P)
Wii U: Mario Kart 8 - fast paced racing, good online matches, outstanding art direction - the must-have game thus far into Wii U's life
PS2: Metal Gear Solid 3 - Never was there a more epic story told in a video game in my opinion. Goes together perfectly with great controls (CQC) and awesome graphics.
PS3: Red Dead Redemption - What a vast world to explore. It really made me feel isolated, like a real western hero.
Dreamcast: Shenmue and Shenmue II - the games are good
