I really haven't kept up with releases, and they are not covered on GB, but has stuff like "Theme Park" etc come out lately (past year). Apart from the SimCity-disaster.
There's Prison Architect, while not exactly a "Theme Park" (well, zapping people is kinda fun) it's not a terrible Prison Tycoon-type game.
Game Dev Tycoon as well, not terrible.
But those are the ones I'm mainly playing really and I really like them so if you wanted something way different I'm sorry.
- Lords of Football looks decent
- Transport Tycoon on iPhone is badass.
- SimCity on iPhone is the simcity that I wanted all along
- Goat Petting Simulator is worth checking out
- Cities in Motion 2 is good
- Hotel Tycoon Resort
- Ski Region Simulator 2012
- Prison Architect
- Tropico 4
- Anno 2070
- Game Dev Tycoon
- Cook, Serve, Delicious
