What new biomes or locations from Star Citizen's lore do you think would be a challenge to tackle, besides the dense forest?

This is a tricky one. I will say there is a bunch of stuff that tech can't handle yet. I will say the forest is the obvious one.

Other stuff like swamps, also; if we do them, then we want to do them right. So we definitely need some more tech there, would be my answer to that, aside from the forests.
