The title reminds me of one of my all time favorite simple hacks.<p>This was from an RTS game circa 2000, can&#x27;t remember which. They were p2p broadcast lockstep as the above, and UDP based. Since the bandwidth is so trivial (boils down to what 10 fingers and a mouse can do), they&#x27;d just repeat the last N messages in every packet as brute force forward error correction. Lose a packet? Just wait for the next one.
