There have been many games that, by virtue of their success, have fundamentally altered gaming for years to come.
Starcraft was hardly the first game to use it's particular style of RTS but it's enduring success (and that of the sister property Warcraft) have ensured that the majority of RTS titles use the same basic mechanics and concepts. Sure, the occasional Dawn of War or Total War style game trickles out but the bulk of the titles use the same concepts and mechanics developed more than a decade ago.
Counterstrike almost certainly popularized the notion of the "realistic shooter" such that the older style epitomized by Unreal Tournament or Quake have all but disappeared from the world.
Halo's vehicle segments and regenerating health has alterned FPS games further, to the point that most games feature regenerating health and often insist upon a vehicle section, even if the game is worse for it (Gears of War for example).
WoW's enduring and astounding success has ensured that virtually every mainstream MMO that has been produced since shares most of the concepts and mechanics of WoW.
This is not to say that any of these examples represent bad games in any way, simply that, because of the success of the titles listed, entire genres have changed to the point that advances have slowed to a crawl. The games themselves are all excellent - so excellent in fact that most games since are heavily influenced as a result.
