    not many games use UDP for their transport

    Citation Needed

    I have never heard of a latency-sensitive game that doesn’t use UDP for inner loop communication. Sure they use TCP for login and server browser, but the actual communication for gameplay almost always uses UDP.

        Minecraft and Terraria use both TCP and UDP, presumably in the way I described (TCP for initial connection, asset download, etc. and UDP for world state sync). Factorio uses UDP exclusively, and implements reliable transport where needed in software.

          Unless it’s changed in the past year which I doubt, Minecraft exclusively uses TCP for client/server communication. I’ve been modding the game for years and am pretty familiar with the protocol. I think it’s actually one of the few which don’t use UDP to some capacity.

              Ah okay, didn’t know that does it differently since I’ve never touched it. Makes me wonder why they used UDP for it but didn’t use it in the Java protocol yet.

          Oops, Factorio moved to UDP.

          Can’t find any UDP implementation or even UDP protocol description for Terraria, while there are implementations of Terraria protocol that use TCP and documentation for it. Basically no evidence of UDP and a lot of evidence of TCP for gameplay.

          Minecraft uses only TCP. Sources: wiki.vg, myself, myself and friend of mine and myself again(no link for now, but two minecraft proxy server implementations)
