I think dungeons could fit in this game and would make many people happy
If you want it replayable make an npc let you reset the dungeon
(the dungeon prize is replaced with a couple of gralats instead once you reset it)
If you dont think Dungeons should fit in an online game like this
1. whats graal? ans: a zelda mmorpg
what does zelda games ALWAYS have? ans: dungeons
2. Get a friend to go beat dungeons on classic (pc)
Then replly to me
...that feeling when you and your friend are solving puzzles together fighting off baddies
feels like true adventure
