Resurrect:
Dungeon Keeper. First 2 games were fantastic, lots of variety of creatures to recruit and rooms to build, and an entertaining dark sense of humour.
KOTOR. The first game is one of the best RPGs I've played, and the best *thing* from the Star Wars franchise as a whole. Second game was a rushed, buggy mess. Haven't played the MMO because I don't do MMOs (I don't think storytelling translates very well into multiplayer). Give me another single player focused game with the quality level of the original.
Half Life. Yeah I think its been gone for long enough that "resurrect" is the appropriate word. We've got no evidence that its in development so it might as well be dead. HL2 is one of the best FPSes I've ever played, fun weapons, smart AI, fantastic pacing. And I need to know how that story ends.
Bury:
COD for obvious reasons. Although to be honest I don't hate it as much as I used to. There was a time that every FPS wanted to be a COD clone and the genre as a whole was going down the toilet. In the last couple of years I've really enjoyed Far Cry 3, Borderlands 2, Metro Last Light, Shadow Warrior, Wolfenstein New Order, probably some others that don't immediately come to mind. COD is still COD but at least the rest of the genre is back on form.
Assassins Creed. I wanted to like this franchise for a long time but the gameplay never really interested me as much as the concept. I played the first 5 games, always thinking "this time will be better". AC2 was fantastic but it just went down hill from there. The thing that annoyed me the most was how little freedom the player gets on missions. AC5 (sorry, "AC3") was just insulting to my intelligence. Everything was so scripted "go and stand here to trigger the mission, now go here, now press this button, now kill that guy with the weapon we've decided you should use, now find this person/object (or activate eagle vision so the game will find it for you) ... oh, you decided to go off-script? De-sync! Restart the mission!"
Struggling to think of a 3rd, generally if I don't like a franchise I'll just ignore it.
