Yeah, the Smackdown! series is the PS2 line.
Review time. Picked up the game yesterday, collectors edition case and all. Have to say, this game doesn't disappoint.

There's obviously some room for improvement but it's miles aheas of last year's SVR, which I still enjoyed very much.
Adding the stamina bar was a great idea. Not only does it add a little more realism with the virtual wrestlers showing fatigue after big spots and selling each other's moves just like their real life counterparts, it also adds a little more strategy and challenge. No longer can you just hit big move after big move and win the match in about a minute, at least not as easily as before. Effective management of the stamina bar will allow you to do damage early and pick up quicker victories, but be wary of wild offense since the CPU reverses a lot more moves. You can even trade a few reversals with your opponent and the whol reversal system seems a lot more precise this year.
Story Mode is unbelievable. I've already finished a season of the Smackdown! story and was very impressed. It's cool to see the characters behaving like themselves, cutting promos in true to life characters instead of having generic dialogue. The only real problem is that it's a bit short compared to the last few games and the character you select will still act a bit generically; I picked the Undertaker and some of the situations and dialogue weren't really right for him, though he did throw in a "Rest in Peace" during the ECW storyline. These are pretty minor complaints though, and the fact there's both RAW and Smackdown! seasons means that there should be plenty of replay value though eventually I know I'll see it all.
GM Mode is a long overdue addition. It's amazing that it's so deep, considering how much work went into the regular story mode. It's the ideal management mode for a wrestling game; make the show profitable, compete for ratings, manage the roster so you're in the black and everyone's happy, assign champions, vacate titles when wrestlers are injured and setup rivalries and promos. Best of all, you can play the matches if you'd like. THQ really outdid themselves here.
So much thought has been put into the game. There's little touches, like being able to put the real belts on the line in exhibition mode so you can change the default champion. There's so much customisation in the Create-a-Wrestler mode this year it's not funny; no longer need you settle for some generic entrances (though it's a shame there's not much in the way of additional music). The Buried Alive/Casket Match was well done. It's very hard to find fault with this game.
Commentary might fall under that category but with a finite number of lines you can record it's going to get repetitive. Sometimes the interruptions are kind of unwelcome but it's probably a bit better than last year. It reminds me of NBA Live and pretty much every other video game with commentary. It suffers the same kind of problems - repetitive after a while, phrases that don't really fit the current action because they've been pulled out too early, etc - but it's still getting better, a step up from the previous title.
As always, unlockables mean you'll be playing every kind of match over and over and Season Mode a few times through so you can get all the Legends and cool stuff for the Locker Room. I'm not the biggest fan of unlockables because it often means some of the best stuff isn't available until you're growing weary of the game but it does make playing exhibition games much more worthwhile. Same goes for the Challenges.
One downer is unlocking Jake the Snake. There's two ways of unlocking him: through a glitch (drafting him in GM Mode) or buying the PSP version, unlocking him there and transferring the data to the PS2 version. I really don't like that idea one bit. I'm a strong believer in each platform's game standing on its own, I want to take advantage of everything a game has to offer without needing to buy the game twice, not to mention a whole new gaming device. I can see why they'd do it because it means more dollars, but I think it's a lousy philosophy.
All in all, this game was that definitely lived up to the hype. THQ have delivered an outstanding title, one not without a few flaws but I don't think I'll notice them much. I'm going to go ahead and give it 9.5/10. I'm honestly that impressed with it.
