Game servers don't verify everything that the client is sending, not everything is replicated / synchronized because when you add AI / physics ect ... it's very heavy on the CPU / bandwidth so off course you can't check everything, every games have exploits because of this reason.
Since you mention MMOs, most or all them don't check for movement even popular ones like WoW.

- Vendan 8y agoEverything needs to be replicated for that stuff, or different clients see different things. Plenty of games DO this, so yes, a game trusting clients is a bug IMO. Yes, WoW doesn't do all the movement serverside, cause it can be expensive. But even WoW does checks for "are you moving faster then you should be".
