Why doesn't anyone run this game on the ps3? Is it not allowed?

It's allowed, I think most people simply choose to play the steam version or use an emulator just because it's easier.

Glad to see you interested in TJ&E! Feel free to send me a Twitch message @ HoodyTwoShoes if you have any questions.

I will do that Hoody. Thank you for the support on learning this game for running and not just casual playing!
