> Once you play at top competitive tier in SC2, every other game is honestly a joke (videogames, not boardgames). What other games REQUIRE you to have 300APM? None, that's how many.
There are plenty of other highly competitive games that are just as difficult as Starcraft, but in different ways.
Dota 2 and Counter-strike are highly team-focused games. You need a crazy amount of teamwork and strategy to compete at high levels.
Quake is a game that requires a godly amount of spatial awareness and ultra-precise twitch precision. Most shots made in the game are faster than the limits of human reaction time to visual stimulus. They are possible because they are responding not only to visual stimulus, but to intuition. Cues like footstep sounds, knowledge of the map, thinking in the mind of your opponent, are all enough information to deduce where exactly to shoot your gun.
Imagine being given 50 milliseconds to click exactly on a single flashing pixel on your screen. People make those type of shots all the time in top-level Quake matches.
Here is a video of a compilation of clips of the two best Bulgarian Quake CPMA players fighting other players, and each other, in 1vs1 matches: http://www.youtube.com/watch?v=q76UNcuKSVY
Most of the shots are made before the enemy is even visible on the screen! And the railgun shots at 1:10 and 3:12 are examples of those one-pixel hits. Not to mention their mastery of the difficult movement system gives them added speed and agility.
