Well for the same reason someone cant bring F Zero X as an example that the PS1 cant do a similar thing.
And no one did. This all started with a negative comparison of FZX's graphics to those of PS1 racers. I simply said "Good luck finding a 60fps racer on PS1 with 30 cars on screen" to point out that the criticism isn't apt, as no similar racer existed on the Playstation. In other words, if you want to criticize FZX as not comparing well to PS1, find a comparable game on PS1. You responded by bringing up a racer that does not have 30 vehicles on screen and isn't even consistently 60 fps...so as far as I can tell, you jumped in with a non-sequiter that failed to make any kind of point, and the conversation consequently degenerated into you trying to make it relevant by imagining what would have happened if the programmers had made it a different game instead. If you're going to make a point, make it, but that means following the discussion more carefully.
