This may be a bit premature, as I haven't actually played a game online yet, but I just have to say...
Thanks to 2k for *finally* giving us the ability to play online against friends.
The game seems to be integrated nicely with steamworks. My online friends from steam showed up in game in both the "play with friends", and the "online league" modes (haven't checked the crew or mypark stuff, as I have never played those modes).
2k had lost me, but just the fact that the options are in the menu now... You have earned your way back into my good graces
2k has also been somewhat responsive to pc requests. First it was the request to pre-load, then for midnight launch, and ronnie2k confirmed both of those things for the pc community.
I would be hesitant to review the quality of online gameplay at this point as it is still day 1, and most games usually suffer online in the early days. But, I will report back on that if anyone is interested.
