Because most games I've played were not released in the year that I played them.
These games are listed in the chronological order that I played them. Completed all of these games, unless otherwise noted or the game isn't really 'complete-able' (e.g. multiplayer-only).
Did not complete; plan to replay and complete with all DLC one day.
Not yet completed; like No More Heroes and, to a slightly lesser extent, Killer7 before it, I love Suda51's games, but I sure do have to force myself to play them.
Didn't complete, got burned out after putting 40-ish hours into it.
Beat about all of the singleplayer stuff and played at least as much multiplayer.
Not exactly a completable game.
Didn't complete; got sick of it.
Didn't complete after my savegames were deleted with my browser cookies.
Multiplayer-only; played it enough to start topping the scoreboard in online games.
Didn't complete; not interesting enough.
Awful first impression; I'll never finish/play any more of this game.
