Those two GUI aren't of the same thing, one is for Real Estate and the other is for diplomacy. Very vague.
I like the GUI that's different from the game's default look, do something unique y'know?
Some people might think otherwise and say that it should conform with the game's art-style of blue bubbly buttons and windows with low-poly everything. I wish you could mod the piss out of it like it was Gmod / Second Life, have you seen the mods for those games?? There's a MASSIVE Star Wars Coruscant city world for Second Life, and there's some great content for Gmod, but with Blockland you can't really pull out a level editor or have each brick have it's own texture.
