My experience is that you want the scenery to be flexible. I once built an elaborate rural scene with a river,a hill and stonewalled fields on a ping pong table. The problem was that having war gamed over it a couple of times it was obvious that to take the high ground always won the game. It became stale pretty quickly.
I now have the scenery from a variety of sources on small sections that can be moved. Therefore you don't get stale scenery.
Just my 2 cents
I have sort of mixed feelings about the Dragon models. On one hand they look very well painted (how do they do it??) on the other hand... I was shopping and saw some of the Dragon 1/35 armor, and there was a lovely T-34 with winter white wash, well worn, it looked great in every way until I saw the slogan on the turret. It was not in cyrillic, but in what looked like sanskrit!
