First, a steady 30 fps is better than shakey 60.
Not if the 'shakey' means that it shakes during the very small amount of gameplay time. Besides, when it comes to games like this where the controls are imperative, 60FPS really helps, even if it sometimes drops to 50 or 45, which is what effectively happens in Jak 2 during it's tearing moments. The responsiveness is just much better. On a technical side of things, 2X framerate meas 2X the polygon count per second, which is also something to consider when judging geometry complaxity.
while its IQ is better than that of JakII
Not really. Jak 2 runs in progressive scan, much like SMS (I assume) does. It also supports wide screen, which I'm not sure if Mario does.
There's a lot to more graphics than pushing a lot of polygons. Super Mario Sunshine is very comparible to JakII in overall visuals.
And there is a lot more to the overal package than just graphics specs alone. I already mentioned the things where Jak 2 *really* excells - the unified streaming world (easily worth a texture donwgrade, IMO, as they have to bestreamed all the time) and the animation, which is simply unmatched among the cartoony looking games, and geometry complexity, which is also hardly matched in games of it's kind.
Mario is a nice looking game, but technically it just doesn't really compare in most aspects, except for that water, where it fares a lot better. Seriusly, if you want to compare something, you are much better off with SFA. I have no idea why even bringing SMS into this when there's SFA as a much more obvious contender.
I hope when you try and argue this, you do it with more experience with the game than when you claimed that couldn't see any differences between the PS2 and Gamecube versions of Viewtiful Joe.
Yes I do. Besides, people with more experience than myself have reported that the visible difference in the VJ on GC and PS2 is the 'amount of blurriness in the zoom mode'. To me that doesn't sound like something worth calling me out on.
