Those radioactive blobs of sh1te that would appear and the tiberium fields, nuke your harvester than go on to crap all over your base ruined TS's multiplayer for me, at least in WC3 you could avoid the random encounters if you wanted to and they didnt agro till you attacked em.
SC is still a great game, i still re-install it now and then and play through the single player game on the human side to get to the level where you have to defend the base from zergs till the evac time, i love building fast and then turning the tables and attacking them instead of just waiting for them to attack
Cardigan or whatever her name was is a right munter tho.
