Call of Duty 4 -> Would still be playable today if it wasn't overrun by hackers, that's how good it is. Too bad the best game by far in the series has no post-launch support at all, and just one map pack. Plus it's the only CoD game to be more popular still than its successor (I'm like 90% sure this is true)... i.e. that it was more played than World at War during world at war's life.
