Or you just write your own game client like china has been doing for WoW for ages.

  It doesn't sound so good Client v1 sends packet A for command Attack So does China Client v1 Developer updates client to v2 and now packet A is non-existent, so no legit user is going to send it so after patch everyone who sends packet A can be banned

    This is currently already the case for cheats. When the game updates then the cheat needs to be updated as well. And you can definitely catch cheaters with the method you mentioned, so many cheats check the game version before doing anything. This means immediately after an update many cheats stop working until they’re updated (or their creator flags the new game version as compatiable)

      I wonder how much success there's been in hiding the version information from visibility by any software... Obviously the cheat developer could just hash the game files directly and halt if there's a discrepancy between the known-vulnerable versions, but it'd be interesting to see whether that was tried with any highly-cheated-in games.
