dont get me wrong, i like TT very much, but it has a lot of little niggles that i dont like, namely the wheelie "power acceleration" trick...you should be able to wheelie a zx10, or most other bikes for that matter with 100+ hp, without having to pull on the bars...and the rolling starts like mentioned above. i dont have too many complaints about the AI, because, no matter how good the AI gets, we will always be better. two player isnt too important to me, because i hate split screen, and the limited number of bikes we could use...well, it sucked. also, spinning the rear tyre needs to be improved. even on my R6, i can spin the rear tire without have to be full throttle. keep in mind, im not smoking the hell out of it, but its slipping and it moves around a lot. in Tt, you have to be smoking the tire for a while before is steps sideways even a little. and then when it snaps back, its way too slow, kinda like a car (gt4 physics maybe to blame). come to think of it, the whole tyre sliding action really isnt realistic in the least. ive never seen a bike slide for more than a second or so, (motogp excluded) and it usually snaps back hard!
hopefully there will be a TT2, and that it will keep the graphics they way they are (or be improved upon) and have a little more motorcycle specific attributes.
