no hyperbole is necessary, the characters in Tekken 2 have 800 polygons each, VF2 arena and characters combined give 560 polygons. Tekken 2 has lighting effects, proper shadows virtua fighter doesn't. These are technical details, if you prefer the VF2 models that's personal taste. Yes Virtua fighter has higher resolution. But Tobal 2 also has it and runs at 90,000 polygons per second, Tobal 1 runs at 120,000 polygons per second against the Virtua Fighter 2 33,600 polygons quads per second.
Sega's AM2 team managed to maxout the Sega Saturn in 95 which is a great achievement but the Playstation is just a more powerful machine.
Virtua Fighter's gameplay is horrible, the team was good at making graphics but terrible at making a fun game. VF2's gameplay is broken, unbalanced, the blows don't have a hit box and what differentiates a strong blow from a weak one is the amount of life, the fights end quickly in around 10 seconds, just a boring 10 characters to play and no FMV scenes, Tekken 2 has the best cutscenes of that year..
Tekken 2 is basically Tekken 3 with simplified graphics, same combos, same fun, if we compare King with Wolf the difference in the quality of the grabs is night and day.
characters have that look for artistic reasons, you can make 4 vf2 characters using 1 from tekken, about the backgrounds being flat what I have to say is that they are the developers' choice, there are many fighting games on the PlayStation with 3D backgrounds at 60fps, on Sega Saturn I don't remember any, which is natural because again, there is no enough juice on the Sega console for that.
