Newtonian Engagement and Metal Gear Solid V

I was recently working through my backlog of things I had filed away to read/watch and I came across this presentation given by Nils Pihl at GDC China in 2013. There’s a lot of good stuff in there, but one new concept stuck out to me. Pihl, whose company Mention LLC consults with game developers, calls it “Newtonian engagement.”

The name is in reference to Isaac Newton’s first law of motion, which essentially states that when an object is set in motion, it will continue that motion until acted upon by an outside force. Fling something into the vacuum of space and it’ll keep going in a line until it gets caught up in an external force like gravity or some astronaut’s face. Bending the idea so that it can be turned to game design, Pihl says that “An engaged player will remain engaged until acted upon by an outside force.” Once we’re engaged, we keep playing until someone calls us to dinner or the clock tells us it’s time to go to work. This triggers what Pihl calls a re-evaluation point. We pause to think, “Should I keep playing, or do something else?” You may be aware of the decision you’re making, or it may happen subconsciously.1

MGS5 makes you go through an awful lot of menus between missions, which hinders engagement.

The insight I thought was interesting was that it’s often the game that provides the player with new information to trigger a re-evaluation point. When you liberate a tower in Assassin’s Creed or peruse a bounty board in The Witcher 3, the games flood you with new information about side quests and points of interest. Faced with this new information –and the fact that you just finished the task you had been engaged in– you now have to pause and consider what to do next. This is a re-evaluation point, and we often decide right then to take a break or go to bed or get something to eat. (Pihls goes into much more detail about the sub-steps that happen at every re-evaluation point and how game developers can use this information to shape players’ perceptions and behavior. Watch the video to get that.)

Some games are much worse at avoiding these re-evaluation points than others. Take Metal Gear Solid V, for example. Whenever you finish a mission in that game, you typically have to exit the battlefield and hop on a helicopter, which takes you into a kind of holding area. You then have to navigate a couple of menus, check on your upgrade research and base developments, select the next mission, listen to briefing, go through several more menues to select your loadouts, sit through a loading screen disguised as a helicopter ride, and then finally get to the next mission.2 all that stuff breaks up any Newtonian engagement you might have and give you an opportunity to think about what to do next.

Games like Shadow of Mordor let you move in and out of quests and objectives without slowing things down.

Now consider another game like Shadow of Mordor. Instead of being broken up into chunks of missions and quests like Destiny is, the game simply has objectives that flow naturally into one another. If you try and tackle a stealth kill objective and fail, the game world just continues on and so do you. There’s a smaller chance of a re-evaluation point happening because your engagement with the game doesn’t hit a brick wall in the form of a “Mission Failed!” screen, a “Press A to try again” option.3 The player’s attention just flows to the next nearby thing in the game world, which might be the waypoint to retry the stealth mission or it might be the arrival of an orcish nemesis. Same thing happens if you succeed in that stealth mission. No backing out through a bunch of menues and hub areas to pick a new objective.

The point is that if a developer wants a game to be engaging, it succeeds more to the extent that it removes such roadblocks and lets our engagement travel in a straight line from one event to another.

Here’s Nils Phil’s whole presentation if you want to dive deeper into the concept:

Footnotes:

1. This is, by the way, why there are no clocks in casinos; they don’t want you noticing how late it’s gotten.
2. And yes, I know you can just run around the open world and do side quests, but those are so far flung you’re still going to open up menues to request a helicopter pickup or at least your horse buddy so you don’t have to walk for 15 minutes.
3. FYI, I also wrote about how this kind of thing also aids in immersion and creating a sense of spatial presence.

5 thoughts on “Newtonian Engagement and Metal Gear Solid V

  1. I always thought that the Assassin’s Creed games were good at this “Newtonian engagement.” The gameplay is very similar to Shadow of Mordor, where you can simply keep playing without having to dive into menus or do anything else that may break the immersion. I’ve been a Metal Gear fan for quite some time, but this explains why MGSV is still sitting on my shelf, collecting dust. Very interesting article!

  2. Something you’re missing here is that there are different kinds of gaming psychologies. Some people will feel more engaged when games don’t force you to step away from play to make a decision, but others can more engaged by being forced to do this. In fact, these “re-evaluation points” can actually be a fun part of the gameplay which can keep a player engaged.

    I, for one, have always felt more engaged when presented with lots of different options (like in MGSV and the Witcher 3) and more likely to lose my engagement when things “flow” in the sense you describe above. I guess for me engagement = not being bored, and being inundated with missions and choices that I’m forced to choose between prevents me from being bored… well, providing the options are interesting, of course. I am generally quite easily bored, however, and have attention deficit issues in many other areas of life. This doesn’t mean I have an atypical psychological gaming profile; there are plenty of people who also enjoy these sort of games *for* these reasons.

  3. I’m curious as to how these engagements could potentially play into anti obsession techniques. This may be a good point to bring to mind that a healthy player is a better player.

  5. Interesting connection to casinos not having clocks. Casinos are also indoors so you can’t see sun rising and setting. I wonder if VR headsets that remove you from your day-lit and sun-setting room would have more Newtonian engagement.
