I posted an XP system in one of the other threads, somewhere. It's premise was pretty much like D&D - 10 fights of your own level to gain a level. More fights if the opponents are lower level, and less if they are higher level. That forces people to seek appropriate fights, because 10 fights against a 20th level bot is going to be more attractive than 1000 against a 1st level bot.
Basically, the closer to a D&D system it can go, the better. I've been making it all as D&D like as I can (thus the monster names, the spell names, the combat moves, the GP, the equipment, the names of the healing potions).
