For a while now I have been taking a look at OD&D with a mind to "Make sense of it." rather than just catalog its faults. Rather than change the rules I want to change the way I look at them. So far I have looked at hit points and armour class as well as the character classes. Now experience gets a look. The original system presented was the now classic but not often used gold for xp.This rewards the players for exploration and survial (perhaps avoiding combat) and can be easily divided between party members. This does fit in with the general simplistic nature of the game but doesn't make sense to me. Why do you get better at fighting or casitng spells (or both) just because you're rich? Is because you can afford reaserch/training? Is it because you are more confident? Seems odd to me. Players want to level up their characters because they get better at what they are used for. The fighter gets better at fighting, the magic-user can cast more spells and the cleric can better turn undead. Each character class has its own role in the game so why not make each class have its own goal for expereince? Fighters get XP for mosters killed or subdued in combat. Magic-users get XP for casting spells. Clerics for turning undead and casting spells. All of this has to be approved by the DM. Spell casters can't level up just by tossing spells around for no reason. And maybe Clerics must have some other goal like getting more followers to their diety.
Yeah this could work.
