If a game gets delayed,it usually gets canned or comes out with an added mp mode/more broken than before.the trade off is usually never good.

Surprised you haven't tried the Dead Space or Bioshock series.Also give The Chronicles of Riddick a try.

I don't consider these the best games of all time but they're my favorite.

1.GTA:San Andreas

2.Bioshock

3.Dead Space

4.Doom

5.Batman:Arkham Asylum

6.Twisted Metal Black

7.Uncharted 2.Among Thieves

8.Killer Instinct(Arcade/SNES)

9.Borderlands

10.Unreal Tornament

Honorable mentions:Red Dead Redemption,The Last of Us,and Escape From Butcher Bay.

Not enough games and waiting for a price drop.Or a Prey 2 announcement.

Super Mario World,Street Fighter 2,Killer Instinct,Twisted Metal 2,Tenchu:Stealth Assassins,Spyro The Dragon.Only games i remember playing during that time frame.

If the price of games went down,I'd consider it.But without the games I'm not interested.Killer Instinct 3 or a good new ip would be a reason for me to buy the next  xbox.
