The ruleset, I played Rise of the Rune Lords and it (the rules) was alright. I just remember I had to bounce between a bunch of different defenses and attack bonuses and everything was a build etc and the math only worked if you got certain items and certain levels. Just was not for me. Oh and my character was frightened nearly every fight and I could hardly do shit except turtle mode and go full defense as my action. And I never confirmed my crits.

Killing monsters as the main source of xp was a 3E-ism, and honestly I dont like that it really is just a monster hunting fight game that used dungeon delving mechanics
