You are incorrect.This is so disingenous. No, it doesn't run sub-30 most of the time, nor does it run at "20 fps." It runs at 30 fps with occasional slowdown when things get intense, just like the saturn version (for example, the saturn version slows down when the rockets explode in toon land).
I'd much rather play a game with more content and a save system than a system that runs at a marginally crisper resolution.
The Saturn version runs at 60 fps with minimal slowdown. Where did you get the idea that it ran at less than 60?
The 3DO version actually DOES run under 30 fps a good amount of the time. It slows down CONSTANTLY.
It was one of the first games I bought when I picked up a 3DO a couple years back and was surprised at how choppy it was. Both the Saturn and PSX versions are 60 fps.
I own all three.
