So I got PS All-Stars Battle Royale in a boxing day sale and it's making me want to get a Vita. I know my game comes with a voucher to download it for free for the Vita. My one question is: are the trophies cross-platform or will I end up with two trophy list streams for the game - one on the Vita and the other on the PS3? I know it's silly but I'm debating on the PS Vita based on this game and a few other games so it's somewhat significant for me.
Much appreciated in advance.
