All actors and actresses reprise their roles for their respective characters on the roster, except Nariko and Jak (who are voiced by Jennifer Hale and Josh Keaton respectively, instead of Anna Torv and Mike Erwin respectively).
The game was very similar to the Super Smash Bros. series, but it has different game mechanics like button action inputs and super levels which really work for a PlayStation fighting game. This alone makes the game feel like less of a Smash Bros. clone, since it does its own spin.
The Super levels are references to each characters' home game. For example:
Heihachi Mishima strapping his opponents to a rocket, similar to his ending in Tekken 5.
Kat transforming into her Panther mode, just like she did at the end of Gravity Rush.
Raiden finding his opponents hidden under cardboard boxes, as he and Snake do in the Metal Gear series.
It was the only non-Smash Bros. video game that you can turn off or on the stage hazards.
The former PlayStation mascot Polygon Man has resurfaced as the final boss in arcade mode, which was a clever, yet unexpected comeback.
The stages have been combined with other PlayStation series like Hades stage from God of War with Patapon, Dojo from PaRappa the Rapper with Killzone and Franzea from LocoRoco with Metal Gear which it was an smart decision.
In arcade mode, you can battle your character's rival, such as Kratos vs Sweet Tooth, Jak and Daxter vs Ratchet and Clank or even Sly Cooper vs Nathan Drake.
Each rivalry is not only given an explanation in universe, but they are also connected in some way, like Jak and Ratchet being prominent PS2 characters created by studios that worked closely together and referenced one other in each other's games.
If you own a copy for the PlayStation 3, you get a free download code for the PlayStation Vita version.
Balancing issues like Kratos is overpowered and Sir Daniel is under-powered with slow movement.
The introduction and ending cut-scenes in arcade mode are only still images. (only Kat's story is presented differently, and she's DLC)
Incredibly similar to Super Smash Bros., Evil Cole was an clone of Cole MacGrath, much like how Luigi is a clone of Mario.
Not many stages.
Unlike Super Smash Bros. it has lack of contents where it only had: Single player for each characters in arcade or challenge mode, Multiplayer for online/offline matches and customization for your fighters like profile pic and background.
Despite Polygon Man finally got his first video game appearance. He didn't do anything where he let the other fighters (known as Polygonal All-Stars) destroy the player while he could transformed into various stage hazards (except for Carmelita Fox, Buzz, Metal Gear RAY, MAWLR, Dr. Nefarious and Songbird) for attack, after the fighters is gone he will just slam his head at the stage. He keeps doing the same thing about three times.
Though SuperBot confirmed that Crash Bandicoot and Spyro could be in the game but Activision (owners of both properties) declined.
Originally, Solid Snake and the original incarnation of Dante was going to be featured as fighters. But both Konami and Capcom has declined but they decided to let them added Raiden and reboot incarnation of Dante. (although, Dante in this has retains some personality traits from his original incarnation)

The default appearances of each character are based on how they looked in their most recent/upcoming game. For example, Nathan Drake is based on how he looked in Uncharted 2, while Cole and Evil Cole are based on their appearances in inFAMOUS 2, Dante appears like his DmC Devil May Cry game, which was few months away before release and Heihatchi looks like his younger design from Tekken Tag Tournament 2
