Starcraft II was huge , buggy mess that get patched everyday, I doubt they can fix it. Its gameplay is reminiscent more of C&C series with emphasis on macro/resources. The only good part is the new editor which is also a huge, buggy mess with unintuitive scripting and poor interface. The scripted maps are the only thing keeping it alive though, even blizzard feels it.

Someday even the dumbest fans get the realization SC2 is inferior to broodwar and leave. Broodwar will live on for decades thanks to private servers.
