In the expensive, devious world of advertising, a successful word of mouth campaign is worth its weight in gold. Building something into your product that's fun to show off and talk about makes the purchase feel justified to the buyer, and instills a sense of "Dude, I want this" in the buyer's friends. You've got to give them something to talk about, though, which is why Sony is making the Vita's Cross Play functionality easier to jump into via free DLC for two of its titles.
Well, free with purchase, we should say. Anyone who buys Hustle Kings for the Vita will be able to download the PS3 version of the game for free, and vice versa. Wipeout 2048 pilots that already own Wipeout HD and its "HD Fury" pack will receive the Vita DLC versions of both at no charge when they're released this spring. Sony describes this as "promotional" pricing, so we doubt free cross-platform transference will always be the norm. For now though, it's a good step towards establishing Cross Play as more than a gimmick in the minds of Vita owners and their friends.
