I think this has a lot more application than just games. I mean, there's archival of buildings, objects, knowledge, record keeping, procedures, etc. People forget how to manufacture items when record keeping isn't done properly or is lost. Now you can accurately scan objects, deconstruct them virtually and figure out how to rebuild things once those who originally built them have long passed on. It's happened already with engine parts with NASA. Military parts and items from WW1 and WW2 even. Think about ancient things like the Pyramids and other monuments (like the Easter Island statues). Today, we're still trying to figure out how things were done back then because we don't have an accurate blueprint or information to go on. However anything we build today, could and should, be archived in 3D with instructions on how it was completed. It preserves knowledge for generations to come.
How about law enforcement? Like scanning and matching criminals in 3D in a searchable database is much more revealing than scanning 2D pictures. It would help for non-criminals too. Say someone dies in some fashion and is partially decomposed. But they got scanned when they got/renewed their drivers license, and now the police can accurately see what the person once looked like and can match their identity.
The more I think about the implications of this, the more excited I become. Couple this technology with 3D printing and you're going to be able to do some really amazing things.
How about the medical field? They're figuring out how to 3D print items
