The PS3 version of Minecraft comes packed with cool stuff: split-screen support for up to four players, online multiplayer for up to eight, Creative mode, Survival mode, and a bundle of Trophies. It’s super fun. If you don’t believe me, get the trial and decide for yourself.
Don't forget though that the PlayStation 4 version of the game is still coming! Mojang promises more details on this version in 2014.
For those interested, here is a handy link to purchase Minecraft: PlayStation 3 Edition direct from the Sony store.
