i was forced to do a blog for computer class and i wrote an article on how terraria is not like minecraft, and how everyone who says it is is stupid.
Problem is, Terraria was actually a cash-in on the Minecraft popularity, note how everybody refers it as Minecraft in 2D.
The game's item sprites were placeholders extremely similar to Minecraft's in an early phase of development, and the main developer has made countless money making schemes such as making a website full of stolen flash games overloaded with advertising.
