I'm very interested in playing this game, as I want to try and get back into fighting games to hype myself up for Ultra Street Fighter IV and Super Smash Bros 4, so I thought I'd try out a ARC System Works game. I'm not sure if BlazBlue: Chrono Phantasma is worth it or not, whereas I've heard VERY good things about this. But there's just one problem: I've NEVER played a Persona game before.
So, here's the question: Is it better to buy 4 and 3 before playing this, or is it OK to just jump right into it? I've heard that it outright spoils the plot of 3, but I'm more concerned about it spoiling the plot of 4.
Any help with this is greatly appreciated!
