Oculus Rift is great - especially now it's got Touch controllers. The Vive got their first, though, which means it's HTC's machine that's currently winning the VR war.
While both Rift and Vive have Steam support - with its whole section dedicated to virtual reality - Vive is the product of collaboration between HTC and Valve, so it tends to benefit more from the raft of Steam titles.
But how do you narrow down that long, long list to the essential games that you can download right now? Why, you simply continue reading this very feature!
Here are the 15 games to download as soon as you get your Vive out of the box.
Additional words by Chris Rowlands
Valve’s involvement in making the Vive is most obvious when you play The Lab – a set of mini-games set in an Aperture Science lab.
None are more than a few minutes long but in their simplicity they show Valve has really grasped what VR is all about, whether it’s the subtle vibration of the controllers as you hold an arrow tense and ready to fire in Longbow, or the way you put a jelly-like globe on your head in order to launch each game.
The best one is Aperture Robot Repair, a Portal-like experience, complete with an appearance from a worse-for-wear Atlas from the second game, that’s both laugh-out-loud funny and staggeringly well put together. More like this please, Valve.

We've played this one a number of times now, and the latest build keeps it firmly at the top of our most wanted list. It's a dogfighting spin-off from the huge (and hugely complicated) Eve MMO, and it's ludicrously gorgeous, fast and exciting.
Multiplayer is at the heart of the game, with teams of fighters facing off against each other, but CCP has confirmed that there's also a single-player story mode and another mode dedicated to simply exploring the game's beautiful recreation of outer space.
Battles are awesomely dramatic, beginning with a Battlestar Galactica-like launch from a huge battleship and involving seat of your pants chases through fleets of cruisers.
The game is already available on Oculus Rift as an early access Founder's Pack, but CCP promises it will also be coming to Vive later this year.

Star Wars: Trials on Tatooine
You’re standing by a landing pad on the desert planet of Tatooine when the Millennium Falcon lands just feet away. R2D2 rolls out while Han Solo tells you over the radio (you never see him in person) that he's delivering a gift from Luke Skywalker.
After a spectacular strafing run by a Tie Fighter, said gift - a lightsaber - pops out of the wee droid’s hatch. As stormtroopers disembark from a nearby shuttle, you grab it and instinctively start deflecting their fire back at them.
After a couple of minutes of what is undeniably the coolest gaming experience you’ve ever had, Han gets the Falcon’s guns online and finishes off the remaining troopers. Then he flies away, the demo is over, and you struggle to wipe the smile off your face for a week.
Trials on Tatooine is only a tech demo right now, but with any luck it will be made available for download before long. Be warned, though: the rig used to power it for press demos contains two Titan X graphics cards costing around £1000 (RM5,539) each, and it's very possible that most computers simply won't be able to run it.
