In my opinion the best northstar tag system would work through three separate systems:

1. Automatic tags requiring no host output: Gameservers would report to masterserver their modified match settings so clients could run filters based on that. Ex: client filters for no_epilogue tag which would only show servers that have run_epilogue set to 0, low_gravity maps to servers with gravity lower than default, etc.
2. Country tags would use a separate field like how https://github.com/R2Northstar/Northstar/issues/41 suggests.
3. Arbitrary string tags could re-use the server description field (or even title) instead of adding a new one, currently the serverbrowser doesn't filter for descriptions but it should be faily easy to implement

My problem with accepting this PR in its current state is that:

1. It's tedious to add tags reflecting your in-game settings and hosts probably will forget to do it or won't even use it at all.
2. Having tags as arbitrary strings is too open and might fail to group servers like the host intends. Ex: someone using brazil vs brasil, EU vs Europe

With this implementation tags become limited and defined by game settings or geographic regions which helps to create a proper filtering UI for the frontend.

If this were the case, how would you decide which "things" are worthy of generating a tag for? How little gravity is low gravity? How slow is slow movement? no_epilogue seems pretty pointless of a tag to me, seeing as epilogue is dependent on gamemode (as far as I'm aware).

I don't mind country tags. It will probably remove some ambiguity/mispellings and ensure that a server location and by extension a way to estimate ping is present on every server.

I agree with the fact that tags are too open, but I don't think the right solution is to search by description. You will then instead end up with huge descriptions reading "tags: x,y,z," as has happened with so many other platforms.
