Garry's Mod vs Spore
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.
Spore
Spore is a pretty unique and addictively fun god-mode-like sandbox game where you get to create a whole new world and fill it with your living creations. As a "god", you can play around with the game's five evolutionary stages, from Cell to Space, and grow an entire space-faring civilization from its very simple beginnings as a single-cell organism. Of course, to develop a civlization, you'll need plenty of tools to help them along and Spore gives all of that to you in an easy-to-use format. You can literally customize everything you like in the game ranging from vehicles that your creations will drive or even buildings that your organisms will live in.Although Spore is essentially a single player game - after all, there can only be one almighty god... and that's you! - the world you've created is shared with other players in the game, so your creations can actually explore new planets and maybe even bump into a hostile race which will force them to make the preparations needed to go to war.
Overall, Spore is an amazingly detailed, civilization-building, sandbox game that allows you to micromanange almost everything if you choose to do so, or you could lay down the groundwork and let things unfold by themselves. Best yet, there is no limit as to how many worlds you can create, so unleash your creativity and your godly powers and develop the ultimate civilization today!
