More arcade-like than any other NBA 2K game; online play is big step down for this series.
Hopefully 2K will tweak the online sliders for this game, but as of right now I've given up trying to play "sim" online. They also removed the 2K rating system, which allowed players to grade their opponents play-style and tendency to quit early. Obviously, this function was originally meant to provide players with optimal matchups, but somehow this was an afterthought this year when designing the online format (no lobbies either?). 2K9 is a HUGE let-down for me this year...
