>>8118969Mate that sounds a bit too big, honestly. Bethesda had trouble filling up Skyrim with meaningful content. A lot of generic bandit camps, you know what I mean. A fangame will have much more trouble...
Personally I'd go for an "open level" style. You know, not fully open world, but not linear. Just have a big open level for at least each wahi , with secrets to find, stuff to come back to when you have more masks, etc.
