I think that kind of thing would be great for your MMORPG. Solo quests, I mean.Instead of just having CNR areas that can be cleared over and over you could have once-a-day repeatable quests that could function as "day jobs" (getting hired to clear monsters out of mines or forests for mining or logging companies, for example, or escorting caravans and dealing with random bandit attacks on the way) that function as short solo quests and give enough XP and gold to be worthwhile, but not so much that it's preferable to finding a group. Having a reason to repeat them would be great for the RP as well, and they'd be good ways to meet up with people of your level for other adventures.
