I have always wanted to try a Forza title but this one looks simply beautiful, the graphics are amazing and the level of realism is fantastic. I really like that it is so detailed that the driving varies with each vehicle and even if you make a modification you will notice it all at once.
I think the same as you, it's a shame not to have split screen and the racing titles were always super fun to play with friends in split screen :D
Let's just hope they fix this in the 6th title xD
