I missed out on the DC, even though I was a Genesis kid and still remember Sega fondly.
Gotta say though, coming back to both it and the Saturn as an adult, I still honestly prefer the Saturn (with the JP library) by a mile. I feel that if you don't like fighting games, the library of arcade ports on the DC isn't nearly as good as the Saturn, and most of the non-arcade titles haven't aged well.
And the stock controller just does not feel good in my hands, to the point where it makes me not want to play DC stuff, especially arcade ports. I know it's quite similar to the Saturn 3D Pad, but that feels way better in my hands. Even the N64 controller is more comfortable for me than the DC controller. I got a MadCatz DreamPad and that helped a bit, at least.
