Actually I reinstalled SC yesterday. Unfortunately for me, I'm getting my ass handed to me most of the time on bnet, even though I've been playing SC quite some on bnet a couple of years ago and A LOT at lans. Tried iccup 2 years ago or smth and didn't really have much chance.
The gameplay is constantly evolving and skill level of the playerbase increasing. ICCup is getting harder and harder with every season too.
