Garry's Mod
Garry's Mod is a sandbox game that brings back the hilarity and joy of being able to simply experiment and have fun. There aren't any objectives in this game; you are simply given the tools you need to play with... just like that time when you get your first Lego set. Being a purely community-driven game, Garry's Mod is quite the multiplayer game. You can hop into any of the created content or game modes and have fun with your friends, except for buy-to-play games in which you'll need to own the base game first. You can also opt to spend time to create new content that you can then share with the community. If you'd rather play in peace, you can play Garry's Mod offline too.Garry's Mod is definitely the sort of game that creative players would enjoy. The amount of stuff you can play there is astounding and of course, you are given absolute freedom to express yourself through your creations if you choose to do so.
