Very awesome room! I love the candy cab + ottomans, I use something pretty similar to store all my controllers in my office. Looks like you've got a really solid collection of good titles, no filler games, and all best of all a nice set of Working Designs games
I actually haven't hung any of my posters yet for the same reason, mine are still in tubes too waiting to be framed. They did a really good job on them too because they're not flimsy at all and printed on very nice paper.
I'm personally a big WD dork as well but stuff seems to be harder to come by these days. I've almost collected almost all the variants (just missing a Silpheed, Raycrisis, and Thunder Force V variant), but I'm glad I started when I did because everything seems to cost more nowadays if it's got their logo on it ;P
