That's one way of protecting against piracy for sure!!
On your other posts, I should point out that while we use our own, targeted, sports engine, one really built from scratch (
) for our sports titles, we do use Unity for other products in our simulation division (firearms, law enforcement, military stuff, etc..).
As I have a technical background I was able to personally evaluate Unity for Playstation3 and decide that it was not ready, we objectively decide what is the best engine for any given project, which is why we do have Unity in-house. In any case, one should not blame one's "tools" for an outcome, a good craftsman will always prevail.
