DiRT Rally: Skill Range and More

Nonsense explained by game design

Published on October 6, 2018

People all around the Internet were praising DiRT Rally for its realism and unforgiving rally driving experience. When trying it, a couple of minutes into the game, I hit huge rock at high speed, my car rolled over several times until stopping upside down. A message popped up saying something like press enter to recover vehicle, which I did, and then I was instantly back to the road, ready to keep racing. Instead of killing the virtual me, the game merely gave me a 15-second penalty. Come on, are they really calling this nonsense a realistic simulation?!

Hitting a post at 140 km/h

Step 1: Accelerate to 140 km/h. Step 2: Hit a power pole. Step 3: Keep racing.

Often, looking at these nonsensical things through the perspective of game design helps to transform some whys in becauses. In my interpretation, this particular case is related with the concept of skill range. More specifically this is a nice example of reducing the skill barrier of the game.

Skill Range

Every game is designed with certain skill levels in mind. When designing a game for children or casual players, you want a very low skill barrier, meaning that even very unskilled players can handle it. But that’s not the case of DiRT Rally: this is a game designed for competitive, highly-skilled players. In my few attempts to race in online events I was flabbergasted by the ridiculously fast times ⚡ ⏲ the top players attain (and by the way, most of them seem to own racing wheels and pedals that cost more than my whole computer!). For this target audience, it makes all the sense to design for a very high skill ceiling. This is how you keep even the most talented and dedicated players motivated to play one more time: they feel they haven’t perfected their skills yet, they know they can achieve an even better performance.

And this is exactly what DiRT Rally does. The driving part of the simulation is truly realistic. Add some challenging tracks, some gravel, ice and snow ❄️, some trees 🌳 🌲 and rocks just outside of the road and you get, indeed, an unforgiving game: even small mistakes can end up in an accident. The design is clearly optimized for the top-end of the skill spectrum. As I just said, this makes sense for this game, but also brings a big risk: the game can turn out to be too hard and frustrating for beginners. If the damage simulation in DiRT was as realistic as the driving simulation, only those who can drive in real rallies would ever finish a stage. And that would be bad, because there aren’t too many rally drivers in the world and the game would probably flop!

Now this is starting to look like a beautiful design: DiRT Rally offers an unforgiving driving experience for the top players but a quite forgiving crashing experience for the rest of us. For a top player, the 15 seconds they get as punishment for a crash are an eternity. A top player that loses 15 seconds is completely out of his challenge. Fifteen seconds or an exploding car 💥 are not much different: in both cases, it’s pretty much game over for them. But it is not game over for the less skilled players. Those can still return to the race and still hope to finish the stage with a good time (for their standards). Perhaps more importantly, they’ll keep racing and improving their skills. Having an increasing number of highly skilled players can only be a good thing for a game that targets this audience.

For sure, I am not one of these highly skilled players DiRT Rally was made for. Nevertheless, I feel great whenever I manage to pull of one of those cool rally-style, sliding turns. Had this game realistic crashes, I would have given up before I had this pleasure even once. In summary, adopting an unrealistic damage model, the designers reduced the skill barrier without compromising the skill ceiling. They widened the skill range without harming their main target audience.

Visual Hierarchies and Control Mapping

Two more quick design-related comments about DiRT. The first is about how tricky creating visual hierarchies can be in practice. In a first look, the game appears to implement a good visual hierarchy, with the most important things appearing with more prominence:

  • The most important thing in the game is the road ahead, which fills most of the screen.
  • The next most important thing are probably the co-driver calls. These are delivered through audio, but also as icons appearing in the center-top of the screen.
  • Then we have other useful (though not critical) information, like the speedometer, tachometer and some indicators of how well the player is doing. These are placed in more peripheral positions around the screen borders.
  • Finally, we have information that is relevant only at certain moments, like the times for the intermediate timing points. These are hidden most of the time, appearing only when they are most useful.

So far, so good. However, for me, playing this game requires absolute concentration (so many times I caught myself thinking about any random stuff and a split-second later I was hitting a tree). And it turns out that most the information on the screen only distracts me. Those intermediate timings popping up on the screen are especially disastrous. “Wow, look at this! I doing good!” Crash. 👎

Too much distracting information on the screen. No wonder I went off-track!

That said, this is all very particular of my own experience. I suspect that better players can cope much better with all these things. The lesson for me is that even a visual hierarchy that looks well-designed can actually fail in practice for some players. And by the way, Paul Coleman and the other DiRT designers seem to be aware of this, as they allow players to enable or disable each of the visual indicators as they want. 👍

Finally, a very brief and kinda obvious comment about control mapping. While a game like this is better played with a steering wheel controller (virtually one-to-one control mapping), we can also play with a game pad 🎮. And when using a game pad, by default, the throttle is mapped to the right analog trigger and the break to the left one. Just like the pedals in a car.
