Same here. That really kills replay value, but I can't help reloading at those points anyway.
Atreides: I meant 90+ hours all three playthroughs combined. I failed at reading comprehension and thought this was just about how many hours one can squeeze out of singleplayer.
Let me rephrase. I'm guessing that, without taking continuous reloads to find about all the possible outcomes on conversations and such into consideration, the sinlgeplayer campaign probably going to last around 30-35 hours for me. I tedn to rush through stuff if it's interesting. Of course, I might get throroughly smitten by ambience, as often happens, and spent hours traipsing over the countryside and drooling at ear- and eyecandy.
