I really shouldn't be doing this, but I made a hex map for an East Marches exploration game for TSR-East. I'm still not done with the rules (although getting close, since it's pretty much just BX/BECMI stuff beyond the classes/spells, and monsters).
In my current West Marches game, using my TSR rules, there's XP for monsters, XP for exploration, and XP for treasure earned.
In Chanbara, there's XP for gold donated to your liege. The idea, if you haven't checked out Chanbara (and you should, it's pretty cool!), is to reinforce the idea of duty to your lord/organization, which is something that I think makes Asian themed gaming a bit different than the wild-west style of normal D&D.
And I just had this epiphany. Give XP as I do in my normal West Marches game. Explore new hexes? XP. Find interesting locations? XP. Fight monsters and defeat them? XP. Bring back treasure? XP. But also, when the players spend that treasure in the home base on potions and scrolls, enchanting weapons or armor, hirelings and henchmen, magical research, or just blow it on carousing, they ALSO get XP. So getting the loot and spending it gets double of just hoarding it.
Benefit? For the players, they level up faster if they choose to do so. For me as DM, it's easier to tempt them with hints of treasures, and things like bandits/thieves/ninja that steal loot, or rust monsters that destroy treasure, become bigger worries.
Drawbacks? None that I can see. Characters who are hoarding their wealth are likely going to spend it eventually.
