People that still say this is a rip-off of Roblox:

Very nice point. Also:
"But it has the same icons!"
From a free set. That is being replaced.
"But it has the same programming language!"
MineCraft uses it too, and its more similar to ROBLOX than this is.
"It has a wiki just like ROBLOX's!"
So do dozens of other sites -- it's from MediaWiki.
