Hey I'm looking for a game

GAMES I ALREADY HAVE: All assassin's creed games 2 Cod, BF3 Skyrim, Saints Row the third Fallout New Vegas (not Fallout 3), oblivion and the mass effect series Portal 2 (hell yeah) Gears, Halo, Fable and SC2. I haven't tried any of the batman games yet, but I will probably get arkham city, unless im convinced to play arkham asylum, btw, are the force unleashed games worth it? Or should I get KOTOR or Battlefront 2 (I used to have those) I honestly don't know what I should get

EDIT: I was deferred by r/games, here is the original post: http://www.reddit.com/r/Games/comments/nuncr/hey_reddit_i_have_a_gamestop_gift_card_good/
