System Shock 2 etc which had co-op mp mainstream. It worked fine and didn't impact upon the singleplayer.
Ares said:Hmmm, I remember a interview with one of the lead developers of SS2 where he mentioned, that in hindsight he would have probably ditched the co-op because it ended up harming the singleplayer in terms of time and development funds. He was not specific but he probably meant that those resources could have been spent refining the SP experience.
