bongo’s advice is excellent.
At the heart of it, the best way to work for a company like Disney, which tries to hire the best programmers and artists available, is to become one of the best programmers or artists available. It’s like the old joke, “Excuse me, can you tell me how to get to Carnegie Hall?” “Practice, practice, practice!”
So, practice. Develop your skills. If your skills lean towards programming, then use those skills to program games. If your skills learn towards designing artwork, then design artwork for games. (If you happen to have skills in both, that’s even better.) Make silly games, fun games, games for you and your friends to have a blast playing. Make little games at first, then maybe try bigger games. Use what you learn in your courses to help you do cooler things in your games. In the game industry, employers like Disney are more impressed by what you have actually done than by what courses you have taken.
If you’re suggesting that Disney make the game called Cogtown, well, I can’t help you there. Large companies like Disney aren’t allowed to accept unsolicited suggestions from outside. The reason is complicated, but boils down to this: it’s possible that Disney is already developing a game called Cogtown. (I’m not saying they are. I wouldn’t be allowed to say if they were or weren’t.) But if Disney came out with a game called Cogtown next month, and someone had written to them earlier and suggested they produce a game called Cogtown, that someone might feel that they deserved some payment for their idea–whether their idea actually had anything to do with the game or not–and try to take Disney to court and demand some money. Even if they don’t win the case (and they probably wouldn’t), it would be expensive for Disney to have to deal with the whole court battle. I know it just sounds nutty, but this sort of thing happens all the time. Large companies like Disney are particularly nervous about this, because people love to sue large companies, since if they win on the off chance, they can get millions of dollars–it’s like winning the lottery.
So Disney just plays it safe, and refuses to take any unsolicited ideas from anywhere. That’s why you can’t get anywhere with TT customer support, and that’s why I have to say “thanks for the idea, but I’m afraid we can’t accept it.” I’m sorry about that.
As for joining the test site, well, the signup list is pretty long, and it doesn’t move that quickly. You’ll get in eventually, but it’ll take a while. You might have better luck on the test site for Pirates, though, if you’re interested in that.
If you reported the hacking fansite to TT customer support, Disney would probably write them a letter and demand they stop.
