For a 1994 console the 3D wasn't bad, but today it looks quite poor. That doesn't mean the games aren't worth a play anymore. For me 'age gracefully' is mainly about how well the presentation of a game has suffered and in that regard the PS has some flaws when it comes to using 3D. The N64 doesn't suffer that much in the 3D department, but it's 2 years younger which doesn't make the comparision really fair
