Just talking with a friend and this topic came up so I decided to post it here. I haven't really played a lot of different games in the past year, but I've played a few through throughly. I'm currently trying to master Ninja Gaiden Black, possibly the hardest game I've ever played.

Off and on over the past year and a half I've played (some replays):

Super Smash 64 (Really good with Ness and Pikachu)
Mario Cart 64 (Learned how to power slide lol)
Zelda OoT (A long time favoriate I can actually beat this entire game in 6 hours)
Metal Gear Solid 2 (Short game, played it on normal I think)
Metal Gear Solid 3 (Beat it on Euro Extreme)
Silent Hill 4: The Room (Totally got owned, worst ending and everything =P)
C&C Generals & Zero Hour (Play a few online tournaments so I'm decent)
Shadow of the Collosus (Amazing game, a bit easy mechanically, only beat it once)
Halo 1 & 2 (Amazing games once again, beat both on Legendary, found all the good glitches/tricks, got some of the skulls, played online with XBC for a month)
Ninja Gaiden Black (Newest game, had this for a month now, beaten story and most of missions on Master)
