Well, this game could introduce you to all the characters and then you can go out and buy the games of your favorites. So I say it is worth it. --- You don't want to know where the babies come from.....
Depends how much you love the genre gameplay-wise, really. If you really like this genre's core aspects, you'll probably find this fun.
Also, seeing as this is your first Sony console, there's SO many good games you need to play. --- Awaiting: GW2, Bioshock: Infinite, The Last of Us, GoW:A, Playstation All-Stars, AC3, Watch Dogs, Beyond. PSN: Ambulance-Chaser
From my personal experience, crossovers are harder to enjoy if you aren't familiar with the characters. I'd wait for reviews and more info. If the fighting engine itself is amazing, go for it. If not, then you may be better off skipping this. --- Brawl FC: 0087 1965 1861 (YAY)
