As for generations, these are 7th generation consoles.
The 6th was the PS2, X-Box and Gamecube, as well as the Dreamcast which came out a *little* earlier and was outspeced, but the hardware was in the same class roughly and provided the same feature set.
The '64, PSX and Saturn were in the 5th generation. The SNES and Genesis in the 4th.
And it goes back further, but all that's before my time.
