No, I mean as in the regular ground tiles. The grassy ones that are the most used tiles in the game. :P Also, can you make it so there's only one of them? Not four. And I mean the metal one; yeah, that's perfectly fine with me.
Well, I won't need new trees for a while XD;. It's good of you to help me, though. Uh, let's start you off with something small... A new ground tile, a new small rock and a new primary signpost? :P
Well, there isn't really much planned for now. It definitely won't be houses or anything like that; it's mostly likely to be signs or trees, just something to make the vegetation in the hack unique.
