The only reason I'm not rating this 5 star is because I didn't actually have an orgasm.
I dig systems that give both the referee and players everything they need in one book. This product accomplishes that nicely. I didn't feel like they were holding anything back or leaving out big gaps to up-sell me later. If Valhalla releases anything else, I'll be buying as a fan, not because I'm strong-armed.
The rules are clear. They provide enormous creative latitude, while allowing the ref to drill down - or not - as desired. The quality of the writing and the artwork was a surprise, far beyond what is normally offered.
I've played a few systems and games that dabble in multi-genre or cross-over, but this is completely different. I'm not sure, but I think this is the only tabletop rpg that is truly multi-genre at its core. It is a goodtime.
Besides the failed orgasm, I'm not giving it five stars because I would have liked to have seen a printable poster sized pdf of the world map, which is beautifully done btw. I also think the pdf should have included a bookmarked outline.
Well done sir.
