FPS game?

So I was casually looking at some FPS games that me and my brother could play together, and…

Minecraft is a shooter game now, I guess.

It has the mechanics of one that could be technically considered one. However, it is still a multiplayer sandbox game.

It can be a fps game if you really want it to become one. Technically Minecraft can be all genres of games
