Well, my friends are playing a game that is a school based game
Like an adventurer became tired of losing people on adventuring. 
Opens a school in order to teach young people how to adventure and not die. 
Has a random generation dungeon. 
Dungeon has like infinite floors and each floor down is harder than the last. 
There are classes and players have to "learn/participate" In them.
Although I don't think I could do all that because I don't really know much. 
There are four houses that represent each "class" of adventure. 
Coin=Rogues
Chalice=healers or Clerics...
Sword=Fighters
Staff=Mage

These schools can be taken like college. 
You get a major and a minor.
Although just having a major as your minor gives you special skills and stuff
