Unless, of course, you're into indie games, in which case the Vita has a treasure trove of little wonders. Many of the best of this generation's independent titles have, strangely, found homes on the Vita: games like Fez, Limbo, Thomas Was Alone, Spelunky and many others like on Sony's handheld and give it a freshness that's totally unique from the Nintendo 3DS. The 3DS feels like Disney-type family fun, while the Vita feels like a hipster's game paradise. Weird pixel-art games and titles that normally live on the PC and mobile make their way to the Vita and take advantage of the handheld's superior game controls. It's an excellent place to play games you haven't gotten around to playing in other places, like a Kindle for books or Netflix for old movies.
Vita: A PS4 accessory, in a sense
The PlayStation Vita does several interesting things if you own a PlayStation 4. It can stream games remotely, either in your home or outside of it, as long as your PS4 is in standby mode. You'll be able to start your system up, tool around in the UI, and even tell your PS4 do start downloads while you're out. (As always, you're home broadband needs to be top-notch, or the experience falls apart.)
Games play surprisingly well when streamed, but the Vita has its drawbacks; for example, the buttons don't exactly match up with what's on the Dual Shock 4 controller, so extra trigger buttons end up getting mapped to rear touch controls. It makes some complicated games like EA's Madden Football a lot less playable. Resogun, a side-scrolling shooter, played fantastically.
The Vita can be used as a second screen for some games, and the home remote-play aspects turn it into the sort of away-from-your-TV gaming device like the Nintendo Wii U GamePad. It can be useful if your main TV is being occupied (trust me), just don't expect a perfect experience with all games.
The Vita will also support PlayStation Now, Sony's streaming-games service launching later this year. How that will work remains to be seen, but these extra perks make the Vita an even better buy for someone already in the PlayStation fold.
Value galore: Cross-play games, plus PS Plus subscription service
There are a lot of ways to get "bonus" or low-cost games on the Vita, starting with the fact that many new PS4 or PS3 games are cross-compatible: buy it once, play it on several systems. This has been true for years, and has helped PS3 or PS4 owners get extra games in their Vita library easily.
But PS Plus, Sony's yearly subscription service, is the best bet of all: that $50 yearly fee means at least two games a month that can be "owned" for as long as you're a paying PS Plus member. Dozens of games, from indies to major releases, have hit the service already. It's a ton more value than anything Nintendo's offered for the 3DS.
If you owned a PSP, there's also a good chance that older downloadable games you may have purchased years ago will already download and play on the Vita, too. (Alas, the old PSP discs will not work with the Vita.) Just make sure you're using the same PSN account.
Get a Vita Slim, or the 'old' original Vita?
Here's the question: do you value a slightly better screen, or easier on-the-go charging, slimness, and improved battery life? The original Vita is basically the same hardware as the new slimmed-down Vita, at least under the hood. The differences come down to the little things. The new slimmer Vita is indeed thinner and lighter, but its biggest advantage is a switch to Micro-USB charging. You can recharge with nearly any spare cable and AC adapter you may already have lying around. The battery life's a bit better, and the Vita now feels more than ready to last a long plane flight.
But the new IPS LCD display's noticeably less vivid than the original Vita's OLED one. If you can get the original Vita for a great price, it's probably a smart move. But if you're going to play a lot of long games on the road, the improved charging will pay dividends.
You don't really need a dedicated handheld game system anymore, now that phones and tablets play so many great games. But tell that to a serious gamer and they'll want to start a fight. There's still value in a standalone, sharply engineered handheld like the PlayStation Vita, provided you like the games it offers. Like a Kindle is for reading, it's a better overall experience for playing games than using a multipurpose device.
And, in the past couple of years, a lot of great games have arrived on the Vita: mobile-style game ports, classic PS1, PSP, and PS2 games, and lots of indie masterpieces. As a handheld game fan myself, I've preferred Nintendo and the 3DS. But lately, I'm finding myself using the Vita instead. Or I alternate. Both systems have nearly completely different game libraries, and different aesthetics: the Nintendo 3DS has the worlds of Mario, Zelda, Kirby, and Donkey Kong, and tons of original, can't-get-anywhere-else gaming, while the PlayStation Vita is a home to PlayStation franchises, interesting throwback games, adult console games, and great-looking indie experiences.
The PlayStation Vita is an indulgence in an age of do-everything portable gadgets. You don't need one to be entertained on a flight or a long car ride. But if you're a serious on-the-go gamer who buys one, something tells me you won't regret it.
