Everyone knows that PlayStation Vita isn’t doing as well as Sony had hoped, but the good news is that the games just keep on coming regardless. Vita may not have mainstream appeal, but what it does have is a hardcore userbase that buys lots and lots of games.

One Way Trip

Strange art style; interesting premise.

To Leave

A magical door.

Rogue Legacy

Roguelike Castlevania.

Metrico

Beautiful and meaningful.

The Binding of Isaac: Rebirth

Super Exploding Zoo

Animals that kill.

Better yet, many of those games still sit on the horizon. There were dozens and dozens of Vita games on the show floor at E3, and, according to this impressive NeoGAF thread, a borderline ridiculous number coming up . It’s enough to get any Vita owner excited.Sony was kind enough to swing by IGN’s office with a debug Vita that allowed us to test out seven upcoming Vita games. You’ll find six of them below. What’s the seventh? Murasaki Baby, which we covered in-depth yesterday To see all six games in action – One Way Trip, To Leave, Rogue Legacy , Metrico, The Binding of Isaac: Rebirth, and Super Exploding Zoo! – watch the video preview above. You can also read about all of them in brief write-ups below.One Way Trip is a strange game, at least if the demo I played is any indication. It’s part adventure game, part action game, and part visual novel, with an interesting premise that makes me want to know more. In short, One Way Trip revolves around brothers who are caught in an unusual, admittedly apocalyptic situation, in which the water supply of their country has been poisoned. Main character Gordon has ingested this deadly water, and as such, he only has six hours to live.How he spends those six hours is, of course, up to you, and it’s here that One Way Trip’s truly unique approach takes root. Amongst a ton of text-heavy conversation and a myriad of choices to be made within those conversations are broader decisions about what you'll do with the precious time you have left. Will you look for a cure? Will you accept your fate and spend time with your family? Will you seek revenge? When you get your hands on it on Vita (or PS4), you can decide for yourself.If you’re looking for a pure gameplay experience with a little story for background, To Leave might appeal to you. Indeed, I really enjoyed my time playing it, and am eager to see more. To Leave revolves around a young boy named Harm, and his special, dimension-traveling door that opens up portals to new locations, including a location known as Candice, which is where To Leave takes place.From here, its gameplay shines through. To Leave is all about flying your door through stages that are nothing more than tracks to speed through. If the door touches anything other than the purple-colored stone faces you occasionally encounter, it’s game over. Making matters more hectic is that a timer is constantly ticking down, and you have to find items in the environment that bolster your clock. To Leave is primed for release in mid-2015 (and will also come to PlayStation 4), and I’m totally intrigued by it.Out of all of the games I got to mess around with, Rogue Legacy is the closest one to being released. In fact, its release date on PlayStation platforms – July 29, 2014 – is right around the corner. I say platforms with a plural because, unlike some of the games on this list, Rogue Legacy is also coming to PlayStation 3 and PlayStation 4 in addition to Vita, and no matter where you play it, you’re bound to enjoy its fast-paced hack-and-slash action.The main hook of Rogue Legacy is, as its name suggests, its roguelike approach. Every time you play it, the layout of Castle Hamson changes, keeping you on your toes. And each time your character dies, you never play as that character again. Rather, you play as a descendant of that character, with randomized statistics, perks, and deficits. Rogue Legacy is going to put its hooks in me for a long time, I suspect.I've spoken about Metrico at length before -- see for yourself -- yet every time I get to play the game, I’m left impressed not only with the heart and soul of the product, but with the little things that I just noticed for the first time. Metrico is, at its core, a puzzle-platformer, but it has a mood and ambiance all its own, and as I’ve said about it many times, there’s a powerful subliminal message hidden underneath it all.I think the major draw of Metrico is its simple delivery and unique mechanics. The graphics are basic, yet beautiful. Music and sound effects aren’t overdone; they fit nicely into the quiet and pensive nature of the game. And since solving puzzles is largely based on your movements – running and jumping to move things around you – there’s a geometric edge to everything you do. The numbers and charts all around the main character aren’t just there by coincidence; they fit in perfectly with Metrico's almost math-based gameplay.This is a game that PC players are plenty familiar with, and in the near future, PlayStation gamers will be, too, as the Binding of Isaac is coming not only to Vita, but to PS4 and PS3 as well in its upgraded “Rebirth” form. What I enjoyed so much about my brief time with Rebirth was how much it’s inspired by the original Zelda on NES – one of my personal old-school favorites – and how it embraces that game’s room-by-room dungeon crawling.With keys to discover, bombs to hoard and use, and non-linear rooms to map as you blindly explore, The Binding of Isaac: Rebirth has the spirit of the old-school, though I found in my short time with the game that it lacks the tight controls of what inspired it. Shooting your weapon is largely mapped to the Vita’s right analog stick, a weird choice considering how small and finicky the nub is. This will likely make me want to play it on console instead, but chances are I’ll acclimate to it the longer I play.When I was at E3, I sampled a great many Vita game for a couple of minutes at a time. One of them was Super Exploding Zoo, and in my notebook, I wrote about how I had no idea what the hell was going on. I was glad I got another crack at it, however, because after being able to spend some time with it away from the loud and boisterous show floor, I got a hang for how it’s played, and it made me appreciate what it’s going for.Super Exploding Zoo is all about using caged animals to protect their unhatched eggs. The thing is, these animals are all... well... explosive. The aliens invading the zoo have no idea what they’re in for as penguin-like creatures blow themselves up on a whim, alligators act as makeshift bridges to let other animals access sealed-off areas, and monkeys gobble up plants to turn themselves into ticking timebombs. Super Exploding Zoo is truly bizarre, and that’s why I’m so interested in it.

So there you have it! Six upcoming Vita games amongst scores and scores of titles still to come to the handheld. Better yet, Sony will be giving us access each month (or so) to a handful of new Vita games to show off in both video and written form. Let us know which ones you want a closer look at in the comments; we’ll try to make your wish a reality.
