Yes but this only works if the question is tagged. For instance, to take your example, there are more result for "zerg" than for "starcraft" which is illogical

Yes but this only works if the question is tagged. For instance, to take your example, there are more result for "zerg" than for "starcraft" which is illogical in my opinion :p You are right that tag gives huge flexibility.. however, maybe a little bit less flexibility with more static section would be easier for gamers. I.e. tagging zerg,rush in the section StarCraft or something like that.
