The amount of times i started 2 and stopped early on. I was in double digits i think.
It had the crappiest launch of any game I remember for Steam users at least. Largely due to them using gigantic files to combat piracy which Steam would have to fully redownload every time anything changed. I spent more time downloading and defragging than actually playing...maybe nine (or more) months later everything was fine and I didn't give a ###### anymore.
