oh boy , another port from a home console to the vita.....
If for some reason you have a vita and no PS3 or 360 then I suppose you can celebrate.
There's two ways of thinking about modern portables. One is, I want good games customized to take full advantage of this hardware. The other is, I want games I like.
Customized game design for portables made sense back in the GB days because A. the system was woefully underpowered, B. games were crazy-expensive, and C. were difficult to produce no matter the target platform. GB/GBA games weren't always great, but they were their own thing and they were all we had. Now, our handheld systems are nearing the power of our desktops (and we're reaching a point where software makers are hardly dying for horsepower, sure Crysis 3 will stress your machine but when you can run a 1080p video stream and have Skype running and be playing Starcraft II AND still have enough power to run the spreadsheet for the work you're supposed to be doing, it's no wonder that Apple is looking to ditch the Intel chipset and just plug a suped-up iPad processor into its future Macs.) We have games that are free to play as well as games that are state of the art but can be found in bargain bins within a month. And we have middleware that makes per-platform production possible with the flip of a switch (of course, you've got to do a lot of optimizing and reskinning to make it work well on a system, but you don't have to start from scratch every time like you used to.) Getting games is incredibly easy, and bold hardware innovation (as innovative as it is, everything Wii U can do is a simple SmartGlass/Android app away from being totally doable on your phone) is making convergence between devices incredibly easy as well.
Nintendo is sticking to the old way with 3DS, and that's doing them good because they are Nintendo. Hardware is moving. But what software is selling? It's Mario Kart, it's Super Mario, and it's the DS versions of Pokemon. Nothing that couldn't be and isn't being done on Wii/Wii U. Even after the creative revolution of the DS, we're back to meat-and-potatoes. They've used the camera a little bit, they've used the touchscreen here and there, they've used the wireless features to play around, but for the most part, they're making traditional games on this untraditional system.
Sony can't go Nintendo's route and expect to succeed, because they are not Nintendo. They already tried with PSP and it didn't go (outside Japan, at least.) Those cool "side-games" like Killzone Liberation and GTA Liberty City Stories, the stuff that Nintendo traffics in, those could all be easily done as $10 PSN or DLC releases. Nothing is keeping Pushmo off Wii U except for choosiness. This avenue won't work for Sony. So they're trying something closer to what Apple and Google are doing, offering the games people want where they want them. Give a choice, explore the options, and hopefully gamers who want both PlayStations will own both and gamers who only want one PlayStation will be happy with the console or the portable. All Sony cares about in the end is that gamers want a PlayStation, getting them to make that choice over everything else is hard enough. Sony's approach of erasing the line between console and portable is not proving itself right now, but it might be the only way for a portable PlayStation to work.
I don't think this will be the case with DOA5+, but always remember, the game that made PSP a blockbuster was in fact a form of a port: Monster Hunter.
It's no longer all about what the system can do for the game, it's what the game can do for the system.
