There are many variants played by scouts all over the world. The different versions: 1) all players get a wool thread around their arm. If the thread is pulled loose from the arm, you are "dead" and need to go back to a "spawn point". This is quite a physical version with some nice wrestling and wolfpack elements. I prefer this version because its visceral. 2) A version where every member gets a certain "rank" from a spawn point. When a player tags another, the ranks must be revealed. This can be a rock paper scissors system or with some wildcards like "mines" that arent allowed to tag, but are deadly for all players except the sapper. You need a card system for this. Many card systems work. 3) a version with paintballs or laser tag. Also fun but you need a lot of gear to do it with a lot of people.

Overall these games are best on long stretches of terrain. There is an optimal terrain width for a nice game. It is biased towards a narrow and long playing field with a lot of good cover interspaced with larger open areas that dont expose the whole width of the field.

Chokepoints can be nice but can also make the game a bit boring. So there is definitely a strong dropoff on the narrower fields.
