I buyed it by 0:30 last night (when I got to the store, at about 23:50, there were already some 50 guys waiting in line to buy it

), and I rushed home to play it.
First thing I did was to drive the Nurb, just to see it. I picked the small autobianchi A112 Abarth (I owned one and I have lasting memories from it, so I decided it to be the first car to drive in GT4).
Then I just browsed all the menus. They're a bit confusing, compared to the GT3 ones, but I guess I will get used to them.
And then, at about 1:30, I decided to start. I didn't use neither the GT3 save (have it at 99%) nor the GT4P one. I want to start from scratch on this one.
So I went for the licenses, and got the first one, with a few golds, but mostly silvers. Now I have two cars (Lupo and Kusabi) in my garage. But I won't start to race until I have all the licenses. Ended by 3:00 AM and decided to stop there, for obvious work-related reasons.
A few thoughts, from the small experience I had last night:
1. the graphics are vastly improved and I had none of the problems some others mentioned.
2. The physics of the cars are also much more realistic. This game isn't as forgiving as GT3 was and you can easily lose control of the cars, even in a straight line.
3. One thing I suspected already and now I know for sure. The DS2 is almost useless in this game. Last night I played with it because I was to eager to start and - with everyone else already sleeping - I tried to be use great discretion in my gaming. So, my DF (not Pro) wheel stayed in the box.
But it is really difficult, with the DS2, to be precise in your steering. Much more than it was with GT3. So, tonight and indeed from now on the DF will be the only option to proceed with GT4.
And someday I will get my DF Pro. Maybe after I do my next planned buy (PS2 related), wich is the Enthusia game.
