I reckon I owe KB more than that last text post...
Tatsunoko Vs. Capcom is (1) a blast, (2) the first VS. Series game in seven years, (3) chock full of fun, colorful characters, and (4) only the third respectable fighting game for the Wii.
Wtf is a Tatsunoko? Learn to Google. (Though, please, do not confuse with Tsuchinoko, the reptillian cryptid and crown jewel of Snake Eater zoological die hards.) Anyways, now you know Tatsunoko is a Japanese animation studio responsible for many of the nation's iconic characters like Speed Racer, Samurai Pizza Cats, and Gatchaman. They reached a deal with Capcom for a VS fighting game intended only for the domestic market, but the huge North American fanbase eventually tempted Tatsunoko and Capcom, and after a ridonk number of licensing issues were resolved, it has been localized for these United States, and is available on an extremely prolific console.
Besides Smash Brawl, the only other significant source of fighting action on the Wii is Guilty Gear XX ^Core (and GGXX^C+, but who's counting?). I've bought my share of Guilty Gear releases, and it's not for everyone. Even with the foreign characters, I think people will be immediately more inclined to delve into Tatsunoko vs. Capcom.
Controls are somewhat of a challenge, though not a dealbreaker. I did not (for once) go out and buy the associated fight stick. I'm sticking it out with the Gamecube controller; the only problem being the joystick and directional pad being woefully inadequate for some of the more technical inputs, like dashes (especially instant air dashes). I've resolved this to some degree by assigning L+M+H to the right trigger simplifying the use of Advancing Guards and Air Dashes. I've got left trigger assigned as L+M+H+P allowing quick use of the Mega Crash (think Guilty Gear's Burst).
The choice of a 2v2 format (instead of MvC2's 3v3) is a better fit for the size of the roster (a respectable 26) and a good place to start for anyone not intimately familiar with tag team fighters. However, if you do know MvC2, you should be able to dive in head first. All you need to pick up are the Baroque cancel, the Variable Aerial Rave, and Mega Crash, and you're up to speed.
So far I've been sticking mostly with Capcom characters, especially Zero and Alex. Jun the Swan, Tekkaman Blade, and Yatterman No.1 have all stood out to me as highlights from Tatsunoko side.
I've unlocked all characters as of Yatterman No.2 last night, and I'll be spending more time in Training and Online before I make another formal post about the merit of this title. But if you ever have or think you may ever pull of an Air Rave, than this is probably a safe buy for you. I know a lot of you out there have Wiis, so seriously consider picking of Tatsunoko vs. Capcom if you have the feeling for the flavor of a fighter. (Oh, and hey, buy it through Killa Blog!)
And I think I heard Shwa got this bad boy... I'll have to hit him up.
