It seems to have a feature like the SteamCloud, or whatever it's called. I played From Dust and it failed, every single time, both logging in and out, to connect to their cloud server but I still had my progress. If I uninstall and reinstall, chances are everything I had would be lost.
This connection to their cloud server is also different from their check-on-start-up-DRM, but there was no way to turn it off either. This made starting and closing the game take a few extra minutes every time.
It's more likely that their kids shouldn't be able to have kids, since one parent would be a human and the other a mutant. So the mutants' kids would be like ligers, whereas the parents would be the lion/tiger. Alternatively, their kids could be like the combination polar bear/grizzly bear offspring, which can reproduce with themselves, and theoretically with either parent species.
Wait, this is going to be a PS3 exclusive? I got a chance to play with it and they were using XBox360 controllers. They even said that it was coming to multiple systems. Did this get changed at some point?
This can be done for much less than the $1500-$2500 price tag you listed if you also make your own projector. That project is pretty simple and cheap (assuming you have an LCD monitor) and the results can be just about as good as purchased projectors. I'm pretty sure that there's even a post here to make one yourself. This would limit what you need to buy to a computer (possibly), a webcam/PSEye, the acrylic, and the LEDs.
