A worthy addition to anyone's fighting game library.
Tatsunoko vs. Capcom: Ultimate All-Stars is a game that few thought would ever see the light of day. The original TvC game, Cross Generation of Heroes, was a Japan-exclusive release that was made with that nation's audience squarely in mind, due largely to half of the roster being made up of characters from the library of animation studio Tatsunoko Production. However, with effort made on the part of both Capcom and Tatsunoko, miles of red tape were cleared and an enhanced version of Tatsunoko vs. Capcom was developed for an international audience.

The biggest new feature added to Ultimate All-Stars is easily online play. While the Nintendo Wi-Fi Connection has its limitations, Capcom did an excellent job in crafting a solid online experience, with leaderboards to track progress and user profiles that allow for a degree of customization in the form of icons that can be unlocked offline. The game features the standard Friends roster built through the exchange of Friend Codes, but players also have the option of tagging each other as rivals, which are tracked on a separate list. Functionally, Rivals matches are similar to Friends matches, only without having to exchange twelve-digit numbers; a definite plus.

Ultimate All-Stars features a roster of 26 fighters. The vast majority of the roster is retained from Cross Generation of Heroes with only one Tatsunoko character removed due to licensing issues. The five new characters exclusive to Ultimate All-Stars need to be unlocked by playing Arcade Mode, but as a whole, the cast provides for host of diverse match-ups. Characters like Capcom's Batsu and Tatsunoko's Yatterman-1 provide good entry points for newcomers, while others, such as Saki and Doronjo have more esoteric movesets that require more practice in order to use effectively. Each side of the roster is also represented by one giant character; the PTX-40A from Lost Planet: Extreme Condition and the titular figure of the anime Golden Warrior Gold Lightan. These oversized fighters are forced to fight by themselves, but their size and power make up for being outnumbered. Notable balance issues in Cross Generation of Heroes such as infinites have also been removed, evening the playing field to a great degree. The balance remains more relaxed than in a standard fighter like Street Fighter IV, but its relaxed in favor of the game's pacing and never feels like it's broken.
Like many Wii games, Tatsunoko vs. Capcom supports multiple control styles. Players can, if they so choose, play the game using either the Wii Remote/Nunchuk combo, GameCube controller, or a sideways Wii Remote using a neutered control scheme. However, the most preferable way to pay is with either a Classic Controller or an arcade stick accessory such as those produced by Hori or Mad Catz.
Regardless of your familiarity with the Tatsunoko characters, if you enjoy fighting games, particularly those of the more manic Versus variety and own a Wii, this is a game that you should really check out. With a full range of features, easy-to-pick up gameplay and a quality online component, Tatsunoko vs. Capcom: Ultimate All-Stars is one of the best, most unique fighting games of this generation on any platform.
