There is a reason that Starcraft 2 took about 12 years to show up.
Any given game (and this probably applies to movies and to TV to some extent) will have an initial title that proves the concept as being worth pursuing, followed by a title that effectively represents the pinnacle of the genre. For 3d Shooters you had Wolfenstien which led to Doom. For MMO's you initially had Ultima online, which gave way to Everquest, and in turn gave way to World of Warcraft. And for RTS games you had Dune which led to Warcraft 2 which led to Starcraft.
Once you have that definitive product, competitors start to back off, realizing that they have no chance to dethrone the reigning king of the genre. The expectations of the fans keep escalating, and since you can never please everyone, you have fans of the genre start to splinter off, or perhaps just get bored. Since sales fall off, the resources for sequels fall off, and that basically buries the genre.
The endgame is that the creators of the 'pinnacle' product eventually stop making new iterations, and that the competitors have usually abandoned that pursuit some time before that point. Eventually no one is making new games in that genre. Metaphorically, the challengers stopped playing the game when it was too difficult to win at it, and the champion stopped only because the rewards for victory were no longer enough to justify the effort.
But the market for that genre still exists, and after about 10 years, a new generation is available to exploit. If the original concept was strong enough, the fans are probably hungry enough that a new iteration should be successful.
