So, while I can't speak for all uses, I'd say USB 3.0, with the right hardware and proper updates, is definitely a viable option for *some* games. I don't use it for that purpose, but, hey, if you can run Dragon Age on NAS over a high-thoroughput network, then I don't see why USB 3.0 would be a problem.
