Those systems introduced 3D gaming, like the Atari 2600 and it's contemporaries introduced home video games. However, there's not that many great games from either of those times. I enjoy playing the Atari generation games because of the intense focus on gameplay and immediacy of the platform, but it's hard to get others interested. I expect the same is true outside of a very few 3d titles from that era between load times, poor textures, bad cameras, etc. (But maybe I'm just old and grumpy)
