Back then I played Warcraft 3 ladder games and I hit my skill ceiling quite fast because my micro was simply too bad/slow. I still very much enjoy real time strategy games. Is there any real time strategy game that is played competitively with an active community where micro is not that essential? (Ruling out Star Craft 2.) Besides real time strategy games, what other games are out there being played competitive with an active community and where clicks-per-second are not too important?
Might be outside of what you’re looking for, but have you considered online chess? It’s fun to learn, doesn’t need quick reflexes, and the playerbase is never going to die.
