I have been browsing the Dwarven Forge Forum for a while and picking up ideas etc. And you often see posts by some very fortunate (and often wealthy) individuals who have some simple stunning setups and gaming rooms.
But I have to take my hat off to Sorn, a chap on the DF forum.. his basement is larger than my house. And the setup he has to play upon, ohhh dear me. I might consider actually doing some one some harm, if it would get me one.. (only kidding, I appal violence in real life).
Seriously, though have a good watch and see. The main table setup is actually mostly Miniature Building Authority stuff. I have a few bits of theirs. They are nice, but pricey, but that goes for Dwarven Forge too.
But I have to say, I would love a gaming basement like his. Having several rooms to put layouts in and store my figures, rather than cramming in what I can where I can and having to generally restrict my purchases to things I can use for a multitude of periods and genre.
Watch and enjoy.. and dream!
