The vehicle physics are in such a bad condition that I don't consider Blockland as a possible racing game or driving simulator. Compared to almost any other game with cars in it, our vehicles behave like stuff. I mean, don't even get me started on planes...
I think Blockland should perfect its core mechanics (building) first, then move on to other stuff such as vehicles. That would differentiate use from the rest of the games on the market and give us a unique niche. Currently, the building in BL is just a glorified version of Minecrafts building system, although with more bricks. But we can't really offer anything to those hardcore builders who use LCad or real LEGO. On the other hand, the vehicle physics and weapon systems are quite bad. So noone is gonna choose BlL over, say, Garry's Mod. There are litterally thousands of games that do shooting and driving better than BL. So in order to make BL appeal to a larger audience, I think improved building mechanics is the way to go.
