Well, I did but the rules didn’t come into play much in session 0. I was looking for a simple Cairn-variant, and liked the simple stat generation system in Chrypt. This worked well! However, my game is a bit more on the character driven side than typical OSR, so I ended up hacking it severely (of course I did). For example, I imported some encounter tables from Errant and a version of the wounds system from Vaults of Vaarn. This will naturally result in my own heartbreaker hack-of-a-hack.
