I've made an interactive demo that lets you tweak the different knobs and see what happens: http://www.gabrielgambetta.com/client-side-prediction-live-d...

I made my own simple multiplayer 2d game to understand this stuff and just want to let you know that your site was invaluable to understanding client side prediction and server side reconciliation! Thanks so much for that!

Once per year; before christmas, someone posts an old trigger for the classical UDP vs. TCP problem.

TL;DR The trick is not to make UDP like TCP, but instead make TCP like UDP.
