The original Shin Megami Tensei game was never officially released in North America -- until now. Atlus parent company Index has posted what looks like an emulated version of the Game Boy port of the first-person RPG on the iOS App Store, for $13.99. From Japan-only release to digitally distributed on your phone -- that's quite a jump in convenience!
Of course, you have to deal with the tiny little issue of the game still being in Japanese. Maybe that part's not so convenient. Combining demons is a pretty delicate art even in your native language!
