I'm pretty close to finishing KOTOR, and I'm really torn on what to play next, but I'll stick by majority.
Keep in mind I have not played any of the games on this list.
XBox - Knights of the Old Republic 2
PS2 - Final Fantasy X
Xbox 360 - Bioshock 2
PS1 - Final Fantasy VIII
Dreamcast - Legacy of Kain Soul Reaver
N64 - Legend of Zelda Ocarina of Time
SNES - Legend of Zelda a Link to the Past
Or, check out my collection and write in a vote... because much of it I haven't played.
Knights of the Old Republic 2 - I've never played it but I've heard that it's not nearly as good as the first one.
Final Fantasy X - This is a good game. I personally like XII better but it's worth a play. The story is cool. Keep in mind that soera has horrible taste in movies and FF games.
Bioshock 2 - Never played it.
Final Fantasy VIII - The first FF game I ever played. I really like it but maybe it's just nostalgia. It's not too difficult.
Legacy of Kain Soul Reaver - This is a great game.
Legend of Zelda Ocarina of Time - A very good game (as part of the LoZ series or otherwise). I can't really get behind all of the love for this game, but I get why there is so much out there. I liked Wind Waker better than OoT
Legend of Zelda a Link to the Past - Hands down the best LoZ game ever. Play this! If you can't sit down for long periods of time just play through a level per night (well, maybe 2/night for the first few since they're pretty easy).
