Has anyone tried this online game?
Beside shooting blood everywhere and doing quests for others, talking to monsters that I’ll never find in real life ... I found this game interesting for surviving ( although are lot’s of topics to be covered ).
A difference from Wikipedia ( you only have content ) this game kind of force you to read about topics / ideas / concepts ( learning without knowing it )
Idea of the game: Win credits for solving questions and use the credits to post your own questions for other users to solve!
Take a look around you can find the concept useful for you.
