Finally got in, spent an hour... not very impressed so far.
You know that first race where you get stuck 'waiting for players'? It turns out to be a race against the AI Lamar; not other people... yea wth.
And if you go to do a job and nobody else is waiting to play it; only way to get back into the game is to drop to the 360 dashboard and restart. Hopefully fixed soon. *EDIT* Seems to be only certain things like Deathmatch.
You pick a car early on; make sure to get a good fast one, because you have to buy all others. You put a 'tracker' on it that makes it yours and have to buy insurance if it is stolen... but the second game I joined, somebody else jumped into my car and took off as soon as I spawned, and the insurance company lines were 'busy'... guess you can grief by simply taking someone else's car, and they can't get it back if you are still in it. *EDIT* You can set a preference to let only you, friends, etc use your personal car (glad I found this)
Kind of a cool aspect; you can be labeled a 'bad sport' if you bail on missions and I guess other things, and if you keep doing that, you can ONLY play with other bad sports.
Pretty laggy. Driving is a lot harder than in single player. On a few missions I literally teleported blocks and blocks away (probably to synch with others, dunno). *EDIT* Next time I played it was a lot smoother.
Thinking this is something I'll only want to play solo for a while by the way I was griefed.. people already flying around in jet planes blowing up players on the ground. Running over you in cars at every opportunity. But this just might be new players messing around.
*EDIT* Turns out you can rank up just playing in a private online instance. You can do races by yourself (not sure if count toward the achievement- doubt it), and you get RP (XP?) for doing things like evading police and losing your wanted level. Still don't understand what the benefit of JP is (job points?).
