In the past couple of weeks I've beat: Two Towers (With all characters + Bonus Level) Return of the King (With all characters + Bonus Level) Enter the Matrix (With both characters) Spider-Man 2 (Even past the 50,000 mark after you beat the actual game)
I can sorta say Lego Star Wars...because I officially beat the 3 story modes with my daughter last night. now I am just going back to get the things that you couldn't get or missed the first time around, to unlock the secret level.
I beat: King dom hearts all keyblades abtained, all bosses beaten , all key holes locked, all characters to level 99 (even world restrict characters, took forever), every trinity point, every dalmation found, beat all tourtaments. I do this sort of thing in every rpg I get.
Half Life Yes the original. I could never stand FPS but this one has caught me!!! Resident evil Remake, Zero, Four FF7 Again..... X-Beyond the Frontier (Finally)
KOTOR II I've gotten a few new games since that time (Jade Empire, Mercenaries), but haven't beaten them yet. Hell, I haven't put in as much time together on both of them that I put in for KOTOR II.
Civilization 3 - not my first win, but I guess it counts. As far as first time beat goes, my most recent was Pirates.
