I would love a virtual tour of the GameHut house: a view of the old tech; a peek at all the promotional material you have stashed away as well as anything you think we'd enjoy taking a look at! I can't be the only one.
Personally, I have a GameStop 3D promo advert for Sonic Adventure DX Director's Cut for the GameCube circa 2003. I can only imagine what you have!
I imagine the office area would probably mostly be the interesting part. The rest is probably regular house-y stuff like anyone else would have, lol.
