For lack of a better term.. I'd love a Career type mode where you start with a small amount of money like in the Challenge modes but then have the option to sell your entire park and start anew carrying over whatever research you had. I'm mainly thinking of the way Prison Architect did it. You'd start with say 10k, build a small minimum security prison, build the value up to 50-100k, sell it, then start a new one with that higher budget. Any thoughts, improvements, criticism welcome.
