Make sure you use first person with this one... once you've maxxed the upgrades on your first vehicle, I would say it becomes a good competitor to MTA race - although the time spent between rounds would break that deal.. MTA you get more races in 30 mins than any other. Similar to Gran Turismo in handling style, it has good competition in it's multiplayer aspect.. check out my profile: http://autoclubrevolution.com/en/profil ... c/DRuGNikT - I highly recommend this game - I'll be playing a lot of it... make sure you add DRuGNikT if you wanna join in.
