Well the point of the other dimension i was talking about would be more of a pure desperate survival rather than building cool stuff. It would be something that would force you to need all these awesome items for combat. Early game the current mobs are fine but once you get your quantum suit you wanna put it to good use! There must be some way of making a challenging area other than making a huge cave in the dark where tons of easy mobs spawn but over time you will get nibbled to death... Wheres the fun in that! =P
So just wanna brainstorm on what would be feasible for an extremely hostile environment.
<snickers evilly> make the robots heal like you do on peaceful mode =P cant play hit and run that way whahaha
