I have a VERY extensive 40k collection. As I live in a small town, I have only three opponents (One friend that rarely plays and two 14 year olds with small collections I have been teaching for a while). As a result I have never built a "proper" board.
Now that the other players are getting their collections to a decent size, I am considering making a table and some terrain. What are some good things to have or avoid? I know large hills with sloped sides are rather hard to keep models on.
Has anyone ever tried to add more of a three dimensional feel with towers with catwalks, multi-level parking structures, or tall bridges? I was thining of making a collapsed suspension bridge. Basically wide enough to drive a tank up, but a dead-end.
