I think the most important thing here isn't what the game industry says you
should do, but what your own stated requirements were. You specifically said
you wanted ordered, guaranteed-delivery data, and that's something that UDP
doesn't give you and that TCP does. If you had some good reason to *avoid*
either of those qualities, perhaps UDP would be appropriate, but since you
need that reliability, and TCP does exactly that, it is the clear winner.
