It is great. Sega Rally Revo was an under rated classic in my book but wen't largely unnoticed (thanks to launching the same week as Halo 3).
At least this time it's only up against..... LA Noire
Still, at 800 points, it's a great game. And it's well worth picking up SRR while you're at it. It can be had for peanuts these days.
Oh, and if it seals the deal, SROA has been developed by Sumo 'Outrun 2' Digital. Or Sega AM9 as I like to consider them.
