This game is fun as simple as. I had Forza 3 and loved that until races were heading for the 30 mins mark and i just got bored i'd start a race and b e bored half way through...and with a racing game thats just not acceptable...so i went out for grid after hearing great stuff by it and wow i was impressed.
Visually i compared this game to forza and at the very least i believe it to be on par if not slightly better.
The sound is of course amazing with the purr of then engine at the start of the race to the revving and roaring of a mid race engine. It's just fantastic.
I kept this review short and snappy and the one word that describes this is fun. Where as Forza is serious and goes by the book - so to speak - Grid just comes straight out, reads the title and thinks "**** that" and rips out up. It's just like that.
In short if you want a racing sim look o Forza, if you want fun and true epic moments Grid is the game.
