Just had a couple of hours last night. First Indian track didn't exactly wow me and I also had to get a feeling of the handling.
The Canadian track really opened up the game. The sense of speed is phenomenal and blasting across the bridge with rumble and fantastic sound effects really got me going.
Then came Scotland - oh wow! At times it just felt so real. It's an overcast track and when the sun suddenly breaks through it almost sends shivers down my spine. At times the lightning makes it hard to see what comes up ahead which intensified the game quite a bit and makes it feel pretty realistic. Night time can be scary at times. And I find the handling really tight and simply love how the cars react to asphalt, dirt etc.
Trying to get below 1:46:00 in the Scotland track proved to be quite a challenge for me. Luckily the game really nails the one-more-time feeling for me, so I finally managed. If you like a racer where you constantly need to perfect your corners, mind the road, bumps, dirt etc. this game really delivers. For me, at least.
Btw, screens don't do it justice - in motion I find it absolutely breathtaking at times. And without HUD it sometimes approaches photorealism. Scotland btw reminded me of the Jerry Bruckheimer intro logo.
