If we take for example, Killer 7 the GameCube version was vastly superior in that it had quick loading times, better framerate and smoother gameplay whereas the PS2 version was the opposite of all this. It just makes me wonder why Sony's PlayStation 2 couldn't have its ports as good as Xbox or GameCube? PS2 had DVD which allowed games to store up to 7GB or so whereas GC's limited to Mini-DVDs with only 1.50GB or around that. I'm not sure how graphically superior either one of them were but PS2 couldn't have been that inferior! Oh, and the PS2 controller had four shoulder buttons (digital triggers obviously) whilst GC had three (well, 2 analogue triggers + 1 shoulder button) and Xbox had two (analogue triggers + black/white buttons). So yeah, someone that knows about this tech stuff please reply as it's something I've always wondered. Thanks.
