> In general it is easy to underestimate the complexity of systems you are not familiar with. Very easy. A key-value store is theoretically easy, “just store data and give it back”, but a distributed / highly reliable key value store is a crazy beast. Collision detection and response seems like a “solved” problem but perk at the code and you’ll find just how many lines of code a basic game spends preventing players from waking through walls.
