WSmith said:4. I may go with 1 GP = 1 XP and 100 XP / HD, cause I don't understand ELs since I haven't tinkered with d20 since 2002.
I like this kind of suggestion, for proper old school experience. But isn't 100 XP/HD a bit much? I thougth that levelling up took 10 x your level XP. A 2 HD monster would then give you XP for 20 levels! Am I missing something?
