I agree with Jessica, 100%. There's no such thing as too old. I'm a 38 year old mother of five. You need a little fantasy now and then to break up the doldrum that is reality, don't you think? In the Sim world, there's no war, no social status, no racism, and only poverty if that's what you choose to have, and then it's easily remedied with a simple cheat code.
If you put your mind to it, I think you'd make a great creator for the game! All it takes is some knowledge, which is easily obtained, and lots of trial and error. Good luck!
