A brief look under the hood of the top engines driving today's PC games
If this year's crop of rocky video game launches has taught us anything, it's that coding video games is hard. Sit through the 30 minute scroll that passes itself off as a credits screen these days and you'll see just how many moving parts go into making today's games. With gigabytes of art assets to create, pages of story to write, hours of dialogue and sound to record, a tangled web of complex behaviors to script, and, oh yeah, actual levels and gameplay to design, one thing is clear: making games isn't all fun and games.
Yet despite the ever-increasing complexity, the creation process is more streamlined than ever. Why? Licensable game engines, tools, and middleware. From specular maps to dynamic shadows, high dynamic range rendering to cloth simulation, from pathfinding to AI reaction behavior, game engines take care of all the nitty-gritty graphical and scripting groundwork and provide a solid (hopefully) codebase for our beloved games. And just like you wouldn't throw a HEMI into a Smart Car, or a power-saving hybrid into a monster truck, knowing which engines excel at which tasks is crucial. So here's a quick look at a cool dozen—a V12, if you will—of the biggest engines and middleware tools in use today.
