I won't pick it up at all. Here's why.. IGN put this in their review, it took me a full readthrough to notice the faults..
Online (Dis) Connection
You see, as cool as it may have sounded to get the online feature that I always wanted, it didn't quite turn out the way I had hoped. Because unlike most of today's other prominent sports titles, be they Madden, NBA Live, or what have you, WWE SmackDown! vs. RAW doesn't offer any type of supplementary online content whatsoever. So while most competitive broadband users out there are used to such features as Internet gaming leagues, automatic ranking systems, downloadable content, and multiplayer support beyond just two players, SmackDown offers none of that -- providing instead, a simplistic two-prong option for either wrestling in a singles head-to-head match or a females-only bra and panties bout.
Regardless of what kind of match they choose to play, however, gamers will never be able to track their win/loss records, defend created belts online, wrestle in tag-team and specialty matches, or even protect their pseudo-identities -- as the GameSpy-powered Interface doesn't allow players to save permanent IDs sever-side. Perhaps most disappointing of all, though, is the fact the broadband-only setup doesn't support USB headsets, only keyboards while in the lobby area.
Where are Eugene, and Gail Kim, and Maven? Why can't we play as Rob Conway, Sylvain Grenier, or Tyson Tomko? And why have Billy Kidman, Funaki, and Johnny Stamboli been overlooked for the second year in a row?
This one right here is what killed my decision
Unfortunately for fans that are looking for additional feature upgrades, SmackDown! vs. RAW just doesn't have them. In fact, in many respects the game has taken a few steps southward. Backstage arenas, for example, have been removed entirely with the exception of a single large environment; and while that solo atmosphere is still highly interactive with plenty of different contact points, it provides nowhere near as much fun as the various backstage levels from Here Comes the Pain did. Additionally, THQ has removed the Cruiserweight, Women's, World Tag Team, and WWE Tag Team championships from career mode altogether (only the WWE, World, Intercontinental, and U.S. titles remain), and the cool stat tracking feature I thought was so helpful last year is gone as well.
career mode seems a lot more linear than it was last year
every wrestler but two (John Cena and a legend) were stripped of their alternate attires
To that, I say..
Only belts that are in season are WWE, World, IC and US title? No alternate costumes? No backstage area? No branching storymode? No tag team online play?

this game.
