If you were quick to buy a PlayStation 4 or Xbox One, you've probably had that horrible moment when you realized that your friends with last-generation systems couldn't join you in online games. You won't have to leave them behind when Skullgirls arrives, however. The fighting game's senior animator, Jonathan Kim, has confirmed that the PS4 version will let you take on PS3 opponents. The notion of a cross-platform strategy isn't completely new, since titles like Guilty Gear Xrd Sign do it. Still, it's helping to establish a welcome trend -- you may not always have to abandon your favorite players to get a new console, or feel pressured to upgrade just to keep up with the Joneses.
