I actually think the jaggies might be a problem to many due to them having the contrast and sharpness turned way up which increases jaggies. Everyone can minimize jaggies by turning down the contrast and sharpness settings to normal and using good cables to connect the PS2 to the TV. On my monitor, even games such as Wipeout (which was said to be quite bad with jaggies) look awesome with almost no jaggies.
And about GT3 looking awesome.. hehe.. just wait till you see the wet-stages (in Rally-mode). Definately the highlight and some of the best visuals to date. (unless of course you\'ve already seen them)
