So, a few comments on the Build Points thread got me wondering: How may groups use a fixed hit-point system (or a non-standard roll), and how many?
I've seen several references to using maximum hit points per die at every level. Personally, after a bad experience with a Fighter with a 13 Con, Improved Toughness, and 37 hit points total, I've been using "average" hit points per die (rounded up, so a d8 = 5, a d10 = 6, etc.). So far it seems to be going well, but I haven't really had a chance to witness it from a non-DM POV. The only thing close was one game where the DM kept hit points "behind the screen", but where my fifth-level Rogue (with no Con bonus) had over 40 hit points. I suspect he was using the "20 hp kicker" from HackMaster, but it kind of defeated the purpose (or, at least, what I was guessing the purpose was) of keeping hp secret once we found out just what huge amounts of punishment our characters could take...
