So you want to make a VR game?

So you want to make a VR game?

The current VR market is desperate for content. Provided you can download a copy of Unreal Engine or Unity and write script that can run at about 60, 90 or 120 frames a second, you can probably sell a barely adequate tech demo for the price of a 6 month old triple-A title.

But please, don’t.

This may be the sexiest image on this blog, ever.

VR is at a critical time of it’s development – we need more content, but that content needs to be amazing. If the VR ecosystem is going to continue to grow, we need high-quality game which takes us out of our humdrum existences to awesome worlds where we perform superhuman feats of epicness.

Let’s assume you want to make a good VR game that will make you a decent return on investment and entertain people. What should you as a developer focus on?

1. Gamer comfort is your number one priority.

Having now played hundreds of hours of VR I can tell you games that give the player a fixed point of reference or gentle motion are the games that are the most comfortable to play. That is put your player in a cockpit, or driver seat, or roller coaster. Eagle Flight achieves this by giving the player a beak. This trick helps the player orientate themselves in 3D space.

Avoid walking – it just leads to VR sickness – “Here They Lie” is a great example of a game ruined by walking. You should instead find a way to swap between an isometric view for navigation tasks and a first-person view for game tasks (like solving puzzles or shooting villains in the face).

Essential for the uncomfortable gamer

2. You need to have a game, not an idea

What is the game I’m playing? Single player Eagle Flight is basically the running around and capturing flag thing that was in Assassin Creed – sure, fun enough for an occasional mission, but utterly repetitive if that’s you’re only trick.

The old rules of level design still matter:

  • You are not the player – you are not the audience, so you need to build the level around them, and assume that they only know what they see. Each level should focus on one of three things: teaching the player something, driving the story forward, or providing the player enjoyment;
  • Your level is too hard – knock 50% of the difficulty;
  • Do not teach with death – players need to be able to make mistakes to learn how to play your game. Death is not a useful way of teaching them about your level. Players need to understand why they’re in jeopardy before you kill them;
  • Do not to put the player on rails, unless you’ve literally put them on rails – you’re better off encouraging the player to move forward, rather than forcing them – unless you’re making some kind of crazy coaster like Rush of Blood, which is more like a demented Lego Land dark ride (in a good way);
  • Make the player feel smart – remember this experience is about them feeling good about life and forgetting their troubles – they need a sense of achievement;
  • Be original – don’t just steal ideas from other games, steal them and then improve on them. What can you add to the level to make it more interesting? What can you take away from the level to make it more fun?
  • If it isn’t fun, it has no place in your game – looking at you RPG devs – seriously, why do I need 17 red bandanas from the pirates guild? And why does this quest giver want 17? Why do only 1 in 3 pirates drop a red bandana? Am I really this desperate for 3 gold? Really?
  • Think about challenges – give your player an enemy, randomly make the challenges harder or easier, make waves of enemies come in groups of three, then give them a rest, etc

3. Keep levels relatively short

Your average player should achieve a mission in 15 to 30 minutes (at least at the begging of your game). As the developer you need to assume that your player is new to VR and that they’re still building up their tolerance. VR sickness is real, as a VR developer you probably left it behind a while ago.

No: you don’t need one of these, but be reasonable.

4. Give your player a 3d model of their controller

The VR Worlds demo disk does this really well – there is a 3d version of the controller in virtual space that tracks the physical controller in the player’s hands. It helps orientate your player in the virtual world.

As an added bonus, if they’re not a hard core gamer, they can look down and see what the buttons are. Consider adding call outs to the controller so that they can see what actions each button performs. If using move controllers as guns, add a laser sight – give make the controls get out of your players way. If you’re making a cockpit style fighter jet game – check out the Call of Duty Jackal Mission for a fabulous missile lock dynamic.

 

5. Your player has left their body behind – your job is to keep it safe.

Consider using fade to black as a non-invasive way of keeping them in the play area.

Think “lap dog” not “gun hound”

6. Low price, cross platform is the only way to go

You need to play the numbers – according to Super Data Research as of December 2016 there were 450,000 HTC Vive headsets, 355,000 Occulus Rift headsets and about 750,000 Sony PSVR Headsets. We also know that Microsoft is planning to produce a cheap consumer VR headset in the next year or so.

All “gaming” VR Headsets sold so far – notice anything?

Now, analyst reports are best guesses, but for the sake of argument, let’s assume your game is going to go gangbusters and get about 1% of the VR market, you’d be looking at about 15,000 sales. Locking yourself into an exclusive on Vive would ship at best 4500 units. Unless you’re able to get a payment from that platform, is not a viable way to make money. And, let’s be honest, those payments all went to Ubisoft and EA already.

Incidentally, given the current state of the VR market, you need your multiplayer to also be cross-platform – locking yourself into one platform will make it much harder for your game to reach the critical mass a good multiplayer environment needs.

So what?

It’s ok to make a game that teaches you how to develop for VR, but be realistic about its commercial value. Gamers want good games for a fair price. If you want my hard-earned money be reasonable. Aim to produce a good, engaging, comfortable game at a $20 price point that will run well on Sony PSVR, HTC Vive and Oculus Rift. Sure that may not make you a millionaire, but consider it an investment in the technology.

Gamers won’t grade you on a curve – there are no points for trying. And, be honest with yourself – have you created a game or a tech demo?

We already have goat simulator for VR – it’s called Eagle Flight.
