I just gave the tech demo a try for the first time, and, I have to say: WOW. I'm playing a mouse and keyboard, so I'm probably not getting the most out of the game, but still. You guys are doing excellent work with this. If you're needing any assistance, I'm willing to provide what I can. I'm a 3D Modeler, and have a JANES Aircraft Recognition Guide laying around my apartment somewhere. If you want examples, just look me up on Deviant Art.
Beyond that, I don't have much more I can really say at this time. The game looks to be coming along well though, so, by all means, keep plugging away at it.
