Perhaps the developers communicated with their netops teams before designing the game protocols? Maybe they came to the conclusion that it's better to run TCP from a security/DDoS perspective than UDP? In other words, the ability to shut off inbound UDP outweighed any theoretical gains from using it in the game? TCP SYN floods are handled with ease today. If you're actually using UDP in your product, you might as well paint "DDoS me" on your homepage.
