How long can a series get by on sheer exploitation of nostalgia intermingled with an appreciation of speed? If you believe that respecting the pat and repackaging it for a new generation is OK and you have good reflexes you will probably enjoy Sonic Generations, the new platformer from publisher SEGA and the developers at Sonic Team. If you believe that what’s old should be left for the past and video games should always innovate then you’d better skip this game, which basically takes all that’s good about Sonic and bundles it in a neat little anniversary package.
