I beg your pardon! I'm ten and a HALF. Shhhhh, don't tell anyone.
Okay then, "What's a good, free game engine that I might dick around with to learn the different aspects of game development with?"
I suspect UDK remains a viable answer, no?
At any rate, no, I do not expect such a project to be done within a half hour. Maybe three-quarters of an hour.
Seriously though, yes, I am very ignorant about game engines. No, I do not expect to churn out a game. I do have the eventual goal of maybe coming up with something (which may take years or in fact never happen), and I figured that, if I'm going to dick around with a game engine, it might as well be an engine that will support the kind of game I would make should I ever have the time/skill/luck/whatever.
Now, of course, I know that it depends less on the engine and more on the dev. Which is good. Thanks again for all your comments, constructive or otherwise ^-^
