Keeping track of each goblin killed, every copper piece picked up. [Sigh.] I just calculated xp for Monday's session, only the third session I've run in Ephemera, and I'm wondering about other ways to do it.
I think something like this would also make it easier to hit what I see as the "level-up sweet spot" where PC's level up once every three sessions or so. It's harder for me to envision that with dozens of "penny packets" of xp floating around. It seems rather simpler with just a handful of major xp gains.
In any case, I do think character achievement has to be included in some way, rather than just flat amounts of xp per session, or just me as GM saying "ok, time to level up." Success of PC endeavors should cause, or at least speed, advancement while lack of success should stop or slow it.
I'll think about this more before even seriously proposing anything to the Monday Night group for our Ephemera sessions.
Anybody have any particular xp system you really like other than monster-and-treasure-based xp?
