Vox: Why video games are made of tiny triangles

"Inside your favorite games — Red Dead Redemption 2, Fortnite, PUBG, Rocket League — you’ll find millions of tiny triangles.
...
Games today are meticulously detailed. They’re mysterious and heartwarming, and colorful and stylized. And that makes them a technical challenge. Though computing power has skyrocketed, gamemakers keep competing to add more detail to their games, pushing the limits of what even the newest technology can compute. Game technology needs to constantly keep up with gamemakers’ creative ambitions.

Triangles are a key part of how these gorgeous, detailed games appear on your screen — the hidden heroes we should all thank as we play. This simple shape helps keep the number of computations needed for each detail as low as possible, allowing the player's computer to process these elaborate games.

When I started in games, we could create assets with polygons that had more than 3 vertices, as long as it was coplanar. This probably still works because when the switch from software rendering to hardware was going on, even the early cards like the S3 or 3DFX would automatically handle it by converting it into triangles.

cos you can always make a flat (coplanar) surface by connecting three points in space. Not necessarily true for any more than three. Simple as that.
