Only the Forza2 trailer has disappointed so far. Looks too mushy and pre-rendered.. unlike the actual first game that looks and plays realistic.
Even for a pre-rendered trailer the forza2 trailer looks worse than real-time PGR3 on a good screen (minus jaggies).. but fortunately I think thats just a concept trailer (about neck-for-neck racing and realistic damage models etc), not a showcase of the final product.
The Forza team will pull an ace out of their sleeve again I'm sure. I was worried about the first game but the full version was every bit as good as it could be.. as in the best and most realistic console racing sim ever.
But, now Forza has competition, GTR 360. Woohooo for us sim fans!
