Ok guys, since the chimera hunt topic is up here, I decided to make a topic about Garry's mod. Garry's mod is very similar to blockland(IMO) In the ways you can build, CI icons, and that it is a sandbox game.
Now some details of the game from wikipedia:
Garry's Mod is a physics sandbox. Unlike regular games there aren't any predefined aims or goals. We give you the tools and leave you to play.
You can spawn objects and connect them with any of the various constraints to create your own contraptions - whether that's a car, a rocket, a catapult or something that doesn't have a name yet - that's up to you.
If you're not too great at construction - don't worry! You can place a variety of characters in silly positions, or have a quick battle with other players.
It's also highly modifiable, which allows third party users to make their own additions. Many new and exciting additions are added to Garry's Mod every day!
Now a quote from some random website stating that Gmod is safe for people younger than 16(or whatever age m is at):
Q:Does Garry's Mod contain violence?
A:It contains guns and dynamite - but that's really not the main aim of the game.
Q:Does Garry's Mod contain love?
A:No
Q:Does Garry's Mod contain bad language?
A:No. Although players can chat to each other if they play online.
