Maybe it would work? Do you have a link?
What I'm trying to accomplish here is a game sort of like Sims, or maybe The Infected? I want the player to be able to use the grid to make walls and such. It's not easy, and wanted to start with the very core mechanics. I also have to build the pre-made, basic world.
I use real models, though, not just blocks. Check out Synty Studios, it's where I get them.
