well with
my awesome suggestion you could actually do something with that boring giant and empty places xD
like maybe a forest with light beams, funky fairys with cliffs caves adventure fun stuffs ect I donno any kind of level design.
But the almost funny thing about GK is that its not made for success, coz if it was really successful and had a lot of players the game would break as there aren't enough monsters (as people don't get like their own copy of the dungeon they enter) or items at shops for everyone (as common stuffs aren't sold by a npc with unlimited stuff... but rare stuffs should of course still be rare xD) and stuffs like that...
