I was going to ask this question as well... now with my answer, I'm seriously disapointed. WHY for the love of Pete, would they take the replay option out!? I'm sure it's not THAT big of a thing to do. IMHO they could get rid of the split screen replays all together... they suck.
Here's another question. Why do my tuned cars suck so bad when I use them for two player battles. I've got them dialed for the single player mode, but get them into VS mode... they suck. Can I fix this?
Why can't I get racing tires for my 700hp+ Skyline in VS. mode? This goes for any of my heavy hitter "street" cars... the supra's hard enough to handle on racing tires... now give me sports tires and I'm lost.
What's the deal with the "quick tune" option? It works on completly different principals then the GT mode tuning system.
Lastly, is there any way to pick a set up like in the older GT games such as "drift" and/or "racing"?
