The key thing to realize is not that PS All-Stars Battle Royale is more fun than any game you have played before, but rather local multiplayer... i.e. playing with friends/family in the same room in a shared play experience is what makes it the most fun.
That is what is so awesome about Nintendo's stubborn insistance to continue to focus more on local multiplayer shared play experiences and not so much on disconnected online play experiences.
They game designs in general can look very simple but when you play with others it is a fun time. Wii Sports was popular for that reason. Super Smash Bros Melee was popular for that reason. New Super Mario Bros U and Nintendo Land on the Wii U right now are delivering that local multiplayer super fun right now.
Don't find out 5+ years from now when some other developer finally makes a similar appeal game on your console of choice.
Get yourself a Wii U and please keep your PS3 because the awesome games Sony makes like Uncharted, God of War, Heavy Rain, and a great many more is not something you should expect from Nintendo or 3rd parties.
