Another benefit of the PS1 being disc based is it being usable as a CD player, back when it came out CDs weren't as common compared to cassette tapes so that would have been quite beneficial.

The PS2 was usable as a DVD player which I consider a very good selling feature, that way you didn't need to buy an additional DVD player and they were quite expensive at the time. With the Xbox did it play DVDs right out of the box or did you need to buy an add on too? Also the PS2 was backwards compatible with PS1 games so you would have access to a large cheap library, not everyone had a PS1 for the previous generation so this was a real benefit.

Another comparison between the Genesis and SNES would be mentioning the backwards compatibility with previous generations, the Genesis could play SMS games and the SNES could play Gameboy games. I would say the SNES won that comparison as there were few good SMS games in North America and the ones that were good were very rare and hard to get.

I'm not sure if the SMS hardware was overall better than the NES, the SMS D-pad sucked whenever I used it and the pause button is on the actual console which isn't convenient. I don't mind the controller when playing games that aren't strict about movement or controls, but anything precise is far more difficult than it should be. I like the SMS far more now than when I started collecting back in the early 2000's, I thought it was mostly junk at the time and most collectors felt the same way then.

The 3DO wasn't really meant to compete with other home consoles, it was meant to compete with Multimedia PCs which were far more expensive at the time. Most of the games were PC ports.

I also don't get the logic of why the SMS is listed as superior to the NES because of the processor speed, by that logic the Genesis should beat out the SNES as it has the faster processor. Sports games played better on the Genesis. I thought the Genesis had larger cart sizes too, or am I wrong about that? It's not very consistent.
