As the game progresses, the platforms you can release your games on will look a bit familiar. The Gameling is the Game Boy, the TES is the NES, the Super TES is obvious. But not only will the consoles look like their real life contemporaries, but they'll perform like them in the market too. This is how you know the Gameling and the Super TES are likely to have good lifecycles, while random systems like the Master V or early PC clones (which aren't the PC) like the G64 won't last long on the market.
