I bought this last week, my first thoughts are that it was pretty good, basically the same as the previous Smackdown games.
However, today I tried online mode, awesome, it is. Virtually all match types are supported online (except the few that excede 4 players), some matches are pretty laggy but the game overall is really fun to play.

PS: free opinion

okie dokie.

moving to smackdown specific.

i own this i think its one of the best ones even it has a relly good online mode. as for leggy matches it only happons when someone has a shotty connection.
