This condition is a mess, not only because it's complex hardcoded logic, but also because it duplicates the logic when to store a replay, which should rather be obtained from the original source (CGame constructor arguments, existence of a ReplayLogger).
If rP17054 had introduced the SaveReplayMetadata function to the ReplayLogger, this line wouldn't have made an appearance, but that's what one learns years later after studying the files more. -> D2211, D2197
