I've played a whole lot of Trollbabe at Spelens Hus, so far with three sessions and five players, although not all of the latter at once. There isn't too much to say! Everything has been berserk and fun and gory and funny and heroic, the whole time.
I think if there's one lesson I could have struck harder in the text, it is that the prep phase is serious. This isn't a good game for GM improvising; you need hard prep. Not a lot of it, but in terms of the listed items in the book, do all of them, all written down. I've definitely seen the difference across the (so far) five locations of play based on the amount of "oh, I'll do that when I get to it" I allowed to slide in, mostly during the second session.
I only recorded the third session in play, so what follows is a brief reflection on the two, and then the recording of the third. I also managed, somehow, to turn up the gain on the microphone without knowing it, so the exact opposite of what we needed happened: it picked up every damn thing happening in a block's radius. But from now on, I'm checking!
