Having come off a Game Dev Tycoon kick due to patch 1.4 I've graduated to the far spergier and more detailed GameBiz 3. It's made by a German or Dane or something whose English is less than perfect so one does things like "Develope game", and the UI is the trouttiest trout I've seen since 1989. On the other hand if you want you can make videogames for damn nearly any system or OS you can imagine. I'm not just talking about the fact the game starts early enough for the ZX Speccy and the C64 to be choices, I mean you can devote yourself to putting out superb games on the Texas Instruments' TI-99/4A or the MSX or VIC-20 if you want to. Better still the game is enormously more reactive than GDT, so if you consistently put great games out on a console that console might start selling better. Or you can make your own - I've not done that yet but I was reading someone else's trip report and he made a console so successful it beat up the SNES and drove the Genesis into oblivion and SEGA exited the console scene like 7 years ahead of schedule.
