Firstly, I would like to say not Minecraft. Here is the list of boxes to tick:
- fun to play
 - fun for audience to watch (i.e. Not Battlefield or CoD)
 - solo not co-op
 - re-play value (such as Binding of Isaac, except that game is a bit dated)
 - original yet famous enough to attract attention
 - NOT something 13/14/15 year olds would watch (I don't want an immature audience)
Optional:
- something that makes commentating easier
 - not a puzzle game (that will make for dreadful commentary)
