Compatibility
Because N-Gage is a software based solution, the first generation MMC games are not compatible with the new platform, though some games are making a comeback in form of a sequel (e.g. System Rush: Evolution) or a remake/port (e.g. Mile High Pinball). Similarly, games developed for this next-gen N-Gage platform do not work on the original N-Gage nor N-Gage QD, adding to the fact that newer S60 software, including the N-Gage client and games, aren't binary-compatible with older S60 devices and vice-versa.
