The title says it all. Ever since the days of Mario and Doom, I have never played a single-player campaign more than once. If I don't do it on legendary the first time or if I don't get all the collectibles I just say "fuck it" and leave it at that. The only game I ever tried playing more than once was Half-Life but the intro sequence was so long that I scrapped that idea.
It's not that I don't enjoy the game the first time around, I simply can't muster up the curiosity to do it again.
