There has been a lot of contradictory posts and speculation from all across the already-large Cube World playing community wondering if they really did copy Minecraft and most of the conclusions end up being: no!
Yes, Picroma did chose to go for the blocky theme, but the contrast in colours and overall feel and objective of the game is completely different. Minecraft's foundations are building when Cube World solely bases it's game on battling and missions. Although, Picroma will be adding house making abilities into the game, the whole concept with be different and the player will have to find and discover schematics across the world instead of individually collecting the materials needed to build your creation. Also, if Cube World is just a copy of Minecraft then why was Notch after the game a while back when he offered a job at Mojang to Picroma -who later quit- if they are basically the same game. Why would notch invest his time and money into a game that he has already successfully created?
