...not questing. I love the idea of wandering around randomly and finding a dungeon, cave, tower, or other site... and going in to clear it. It would then be marked as "Cleared" in-game. No quest required; just combat-themed exploration.
There's some pretty cool technology out there in MMO-land:
- Wow has "challenge mode" where your gear is scaled to a particular level; and GW2 and other new MMOs have a fairly robust Mentor mode, where your whole character is scaled in power. Oblivion had scaling of mobs; that's seemed less fun.
- Rift and GW2 have quest-like rewards that appear just for taking part in events.
- Wow's Timeless Isle has creatures who increase HP based on how many people are in combat with them.
So consider this:
I am level... 10. I see an entrance to a cave in a level 10 zone, and go into it. I have no quests there; perhaps there aren't any quests for that location at all. I spend 15 or 30 minutes clearing it out, and receive a quest-type reward of XP, gold, etc. Inside the minidungeon were traps, monsters, maybe a minor puzzle or two. With the xp from doing these little dungeons, I don't need to do all the sidequests offered in the zone.
To make minidungeons more interesting, perhaps entering as a group would increase the power of the mobs, or maybe... I dunno, maybe people here have ideas to add.
