I love it ....... and hate it.
I have a blast online with friends, but for example tonight at Canada in career mode, I spent a LOT of time swearing at the screen. Quali 2 in the rain screwed it for me, I couldn't touch the AI times and started 17th. This made it a very tough race, but I could only get 12th, after spinning off the inside kerb at the hairpin, and getting a drive-through as punishment, just to rub salt into the wound.
The corrupt game save has hit me 7 times now, and I lost data in 2 of them. That is frustrating, especially as I had switched off Autosave, and have a scheduled task which backs up my save folder every 2 hours ....... all day!
There as so many good things about the game though, that it outweighs the negatives at the moment. It was money well spent and I don't regret it. As usual with most software nowadays, I yearn for a GOOD patch, and hope they can improve on and fix the major flaws.
