My guess is that in the next 2-4 years (due to the next gen) an Xbox 360 emulator will be released, and then we can resume playing S1-S3 to our hearts content. That's if something else isn't made to satisfy us in that timeframe. At that point we could probably be able to mod it and shit like that to get dope-ass parks.
I'll probably be out of college by then haha
