What do you think about it?
It probably would take a ton of server space for Fatshark save all that data. Additionally, querying that data would take a lot of servers and thus would probably be pretty expensive. As an exercise, you should calculate how much space your idea would actually take. You could look up the data from V1 and roughly triple it to get a sense of the number of games that have been played. From there just calculate the number of bytes each piece of info that you want to be saved and multiply it all out.
i like this idea of having global stats like a total rats killed like in the beta, but it’s a nice-to-have which will cost fatshark some valuable production time like @philippe.david pointed out.
I’m sure they are already storing that piece of data, it’s just a single number. They get that info at the end of every match.
