There is tonns of games which use tags in a missleading manner.

First, it requires make tag terms list clear for understanding.

Second, it requires to sort them by propperty specifics, like type of coop, setting genre, i.e. you cannot put Survival and BattleRoyale for the same game, unless it has reach element of Survival, like within wipe. Yes, you are SURVIVE during fixed session in BR, but in this case you should call SURVIVAL all games where you lose if die. So tags should formally exclude usage of some other tags, so people whio do not like BR games will not get them as irrelevant result of bordering tags.

And third, it requires to estimate how strong would be tagged aspect match, i.e. with 7 steam-symbol rating.
