Garry’s mod is one of the most sold games for Linux on Steam, so I’ve decided to publish this review of the game, first published on devtome.com
Garry’s Mod, developed by Facepunch is without a doubt one of the most enjoyable and hilarious games that I have ever played. Out of the box, the game is perhaps one of the ultimate sandbox games available anywhere. You spawn in the middle of an open area that you choose and you can spawn in just about any item or NPC that you can think of. This game is also probably one of the best physics simulators available. The entire game revolves around physics. In this game you are able to do whatever you heart desires and although I say that with a lot of different games, I truly mean it with Garry’s Mod. Whatever you want. If you want to build an airplane out of a bathtub and some planks of wood, then be my guest. You can simply spawn in the materials that you want and then use tools to “weld” them together. Using weight tools you can make these items very light, which will allow them to become airborne. This game definitely deserves lots of praise.
