Push Square: "LittleBigPlanet 2’s hotly anticipated cross-controller add-on launches later today in North America (tomorrow in Europe), and we’ve already been lucky enough to experience the opening couple of stages. For those out of the loop, the $4.99/€4.99 expansion adds several new cross-controller levels to the PlayStation 3 game. It also implements all of the tools that you’ll need to construct your own dual screen experiences, which can then be shared with the title’s online community. You won’t need the full expansion pack in order to play the user created stages, but you’ll still need pockets deeper than Simon Cowell in order to get set-up."
This type of gameplay needs a Vita and a PS3 which makes the potential customers much lower because you don't know exactly how many customers there are. You also run into issues like developers who may want to charge twice for the software, one for Vita and one for the PS3. Again that's a lot to ask and expect to become mainstream. There are simply more hurdles in place for Sony to benefit. We saw what happened with the Playstation Move and how niche that device was. Wonderful product (much like Vita) but hardly any software that really took advantage of it.
There was also that leak/rumor (with pics!) awhile back about the controller for the Steambox having an integrated screen.
I consider this to be quite a good mix. there is literally something in there for everyone besides an RPG only player. I've had the option to use it on a suprising number of games I own and it can create an even more engaging experience when implemented properly.
I hope that the vita will at least see this many games with the option to use it as a second screen.
What I mean is, do you need someone playing with you? I want to get it, but I don't have anyone to play with.
I'm talking about the packs of course, I'm sure the online created stages should be playable by one person.
