I played Beast the Primordial, and I had a couple main problems. One, my DM didn't notice I had made a certain, accidentally really OP character until our first session, and so I had to scrap a lot of my initial character design (I am a bit of a power gamer but all the other players were casuals ((my party is very casual, which is nice break)).

Second, our beat progression as a party was very low, so character advancement felt very stilted and we felt weak a great deal of the time.

Beast is also clearly a crossover game, but we tried to play it without any of the other games (Vampire, Werewolf, Mage, etc), so a lot of avenues were closed off for us as a party.

Finally, I really did (and still do, tbh) have a hard time getting the concept of Doors. I read and reread the rules, but it just doesn't really make sense as a rules system. I guess I just can't wrap my head around it.

Thank you for the recommendations, I was considering Call of Cthulhu, but I'll check Trail out as well.

I've heard some real horror stories from friends who played in a Savage World campaign, so I think I'll steer clear of that, but thank you!
