i wrote this in the first post, but here again. All stuff is between 200 ~ 900 polys. Why...one of all it is for use in a low powerfull development like Blitz 3D, otherwise is the stuff for Phone Tools. But in 3DGS you can take this for a Frogger Clone or whatever.
Your models only would be good for display in far distance
Yes....bingo....this is the reason, your example is not his, what i will do. ONLY LOWPOLY!!!
