Pretty stupid you can't make a party and all join a quick match or something. Kinda works if you all stand on the same blue circle in freemode or if you start one up, immediately close it to everybody and then invite who you want.
I do occasionally crash (ATI Card w/ Latest Drivers) when I hit LB with a controller to aim while driving since I switch to my controller to drive. It doesn't always happen, but I've had that happen about four times I think. Also crashed twice in online, one when switching maps during TDM and another when exiting from a lobby post-game of TDM.
Other than that, it runs and plays great. May be looking for some people for some heists as well, so I'll throw my Rockstar Social Profile link out:

I prefer to use my TeamSpeak 3 server as I rent it for friends and I.
