Neither game copied from each other and the people who say so are idiotic children.
This includes Setro2.
Blockland is no better than Roblox and Roblox is no better than Blockland.
Shut up already.
Roblox is aimed at a younger community, so some it's users might not be as old or progressed as us, although it doesn't make it a bad game.
Setro2 is pretty dumb to actually take sides in this.
Just because a game is similar to another and newer does not mean it copied it.
If we use your logic, Blockland would've copied Lego, and so would've pretty much every other building game in the world.
What a great system.
Rather than get on the opposing game to yell at them and tell them they suck, why don't you shut the hell up and go play the game you like.
