"PlayStation All-Stars Battle Royale has received reviews that ranged from average to generally favorable. Critics praised the game's multiplayer and fighting mechanics, but criticized its lack of content, still images in campaign mode and few cut scenes. The use of super moves as the only way to defeat a player had mixed reception. While some critics thought it lacked depth, others believed that filling up the meter to land a knock-out added strategy to an otherwise only decent fighting experience. The game currently holds a 74 score for the PlayStation 3 version and a 75 score for the PS Vita version on Metacritic."
They should seriously buckle down and take another crack at it if you ask me, although maybe not have such a questionable roster of "all-stars", for example; Big Daddy... in no way would I EVER consider him a PlayStation all-star, lol.
I mean... look at the original Bioshock, it was literally an X360 exclusive for the first year of being on the market, it wasn't even on the system that considered him an All Star.
One thing that has to be said about PSASBR was that intro was pretty awesome the way it was put together.
