For those who want to get to the point quick, buy this game, and if you can afford it, buy the Deluxe Edition. Driver: San Francisco is an extremely well made and outrageously enjoyable title well worth it's full price or lower. Every car model is licensed, from old family sedans to powerful muscle cars to zippy super cars, and everything in between. Driving a heavy vehichle like a bus or a transport truck feels fun and weighty, like your really pushing the car to its limits as you perform burnouts, jumps, and weave between oncoming traffic.
The story so far has been relatively camp, the usual villian breaks out of jail and you are the only one who can stop him, but takes interesting new directions in how it tells that story. One of my favorite parts is how all cutscenes use a fusion of CGI for charachters talking mixed with actual in engine gameplay (Which means you aren't looking at a cutscene that's been prettied up and doesn't look like what you'll see in game.)
For those worried about the Uplay integration, don't be. I was originally of the camp that hated the service, but so long as your system is able to run the game you shouldn't have too much issue with it. Would I rather it be removed entirely? Yes, but I'll give Ubisoft a pass with this, so long as the service isn't discontinued and the game breaks because of it.
For those who need a score, I'll give the game a 9/10.
