This could have been something great. If you were a kid during the early days of gaming, the idea of a game that celebrates each era in turn is a nostalgia trip the likes of which will would bring a tear to the biggest retrogamer's eye. If you are not so old, then it would be worth it just to see what gaming was like once. But this, as much as it wants to be, is not that game. It starts as it, absolutely, but by the time you are done, it falls from grace in repetition and, ultimately breaking down entirely into a mess nothing short of patching it at a code level will fix.... just in time to ruin the end of your experience.
