There are a number of games that support crossplay on both Vita and PS3. Some games, like MotorStorm RC, include both the Vita and PS3 versions in one purchase. However, other games, like the recently-released Metal Gear Solid: HD Collection, require separate purchases to take advantage of any crossplay features.

It's unlikely many gamers are taking advantage of Vita's crossplay features with games that require multiple purchases. For example, if PlayStation All-Stars is fully priced on both Vita and PS3, gamers will have to pay over $100 for the luxury of playing one game across two platforms. That doesn't sound attractive--but Sony may have found a solution.

“Imagine that as part of PlayStation Plus, every time you bought a game on either PS3 or PS Vita, you would be entitled to get the game on the other console absolutely free," a new survey spotted by IGN reads. "So, if you bought Resistance on PS Vita, you could download Resistance on PS3 for free. Or if you got FIFA on PS3, you could download the PS Vita version for free.”

By unlocking free versions of the Vita game via PlayStation Plus, Sony would make it much easier for gamers to take advantage of crossplay features--and introduce Plus to Vita gamers. It gives gamers more reason to pay the $50 annual fee, and doesn't dilute the perceived value of the Vita version of games.

While the idea certainly sounds smart, ideas found in surveys don't necessarily come true. For example, Sony considered bundling Call of Duty Elite into PlayStation Plus. While that didn't come to fruition, PlayStation Plus did recently offer a large number of full retail games.
