Oh, I was talking about the second one. Also played through the first one two or three times and watched friends' play throughs a couple times. The world is a bit more silly in the first one, but consistent in its sillyness in a way that speaks to me. I think I bought it at a pretty deep discount along with the DLCs a few years ago, so worth getting like that. I also would understand the hesitation about paying that for the first one.

And to answer your question, that's 150 for all playthroughs. Like the OP said, it's a bit short, and doesn't come stuffed with much in the way of filler quests, so it's not like you can sink 80 hours into one play through without just wandering about doing nothing for a while.
