Blockland vs Garry's Mod
Blockland
Blockland may be a voxel-based sandbox game in name, same as games like Minecraft, Roblox and others, but in reality, the game is a whole lot more unique due to its Lego-like features. In fact, due to its looks, many have likened the game to the unfortunately shuttered Lego Minifigures Online. Playable in single player or multiplayer, the game allows its players to unleash their creativity by creating literally anything they can think of. The game also has tons of different blocks, textures and assets (pre-made stuff) to cater to their creative needs, allowing players to come up with the most exciting mini-games and mazes as well as beautiful locations for themselves and their friends to hang out at. Players can even drive cars (sometimes vertically up the wall of a building, breaking all rules of perceived gravity in the game), ride bikes, pilot planes, and more.Although the game is no longer getting updates and apparently its community has been dwindling, Blockland is still an amazing game that answers the question of what Minecraft would look like if its "Lego-fied".

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.
