The Meaning of Life, the Universe, and Everything.
MCPS3 is very awesome but there is things that are missing in it! Like unlimited worlds i csn't understand why MCPE have unlimited worlds and MCPS3 don't have them it should be at the that MCPS3 have unlimited worlds and MCPE limited ones or both of them have unlimited worlds!
Simple. go to the store, lay down some fat stacks of cash, and BAM! You got yourself a PS4 (or Xbox One if you prefer). Even if PS3 had unlimited worlds, you wouldn't want to use them. PS3's are too outdated to handle such an immense amount of data all at once and your system would crash/lag often trying to manage.
Actually it could handle it since not every thing is always loaded at once you have several MMO style games on ps3 as is. They honestly use more data loaded at once than minecraft does ...But its limits placed on the systems that wont allow it to be done.
