So far, pretty much everything survived the big move intact.
ARCADES: Donkey Kong 3 & Championship Shootout made it ok. I have powered up the MAME cabinet yet, but my D&D Tower of Doom cabinet didn't survive. Initial attempts to turn it on have resulted in gibberish on the screen. I haven't had time to really play with it much, but I'm not optimistic.
RPG: My D&D collection made it ok. A few crushed boxes here and there had me worried, but the contents all look ok... so that's a relief. I have most of it shelved now, only a few stragglers here and there.
GAME SYSTEMS: I brought the 360 in the jeep with me, so I know it's ok... I haven't actually seen the box with all the other stuff yet, but I'll probably get to it this weekend. The projector rode with me as well, so I know it's ok too.
Speaking of projector, the previous owners of the house had a ceiling mounted projector (which they took, of course, and left me 4 oddly placed bolts sticking out of the ceiling. Apparently he made the mount himself, so I don't think it will actually line up with anything... so I'll be making my own as well I guess. Looks like I'll be hitting Lowes this weekend. Fortunately I found an article that covers a lot of what I need, here.
PETS: All the critters survived. 2 Cats, 1 Iguana, 1 Leopard Gecko, 3 Frogs, 1 Toad, 1 ZombieFish, 1 Newt and apparently we have wild rabbits in the back yard.
Everything made it ok, as far as I know. I'm pretty bummed about the D&D Arcade, but I might be able to fix it. I just haven't had time to really dig into it. On the upside, I finally got a 4 player cabinet for my other D&D game: Shadow Over Mystara, so I have a nice little garage project to work on.
