Minecraftbut. That's the term that Rock, Paper, Shotgun's Alice O'Connor recently coined (in the same vein as roguelike) to save us all from having to say "It's like Minecraft, but..." one more lousy time. It might just be my favorite piece of gaming shorthand since "Abilitease".
Cubic Castles (a new free-to-play game that you can snag on Steam, the iOS App Store or straight from their website) is one such Minecraftbut, with an emphasis on building, crafting, puzzle platforming, and easily shared massively-multiplayer worlds. The problem with writing about Minecraftbut's is that defining one thing based largely on how it's different from that other thing is a difficult and often unhelpful way to explain any thing. There's a comparison to be made... But it's much better just to see the thing in action for yourself.
With that in mind, I did a dreadfully unprofessional (it's been a loooong week, you guys) stream of Cubic Castles earlier today so I could share the experience with you. Check it out:
