Windforge is going to blow your mind. On the surface it sounds like a garden variety Terraria or Minecraft clone with a steampunk coat of paint. Spend an hour with the game and you'll realize it's so very much more than that. Windforge is a sidescrolling role playing game that lets you build and fly an airship and craft tons of items, weapons and parts. Everything in the environment is destructible, giving you a tremendous sense of freedom and making just about every other exploration game look restrictive by comparison.

Scribblenauts Unlimited is a new and improved release in the Scribblenauts line from 5th Cell Media. Giving you the power to create objects at will, you embark on a quest to bring happiness to the world, helping people in need by granting them objects from your magic notebook. That's all fine and good and such, but the fact of the matter is you can create just about anything you want, so while that pedestrian is in dire need of a glass of water, wouldn't it be so much more fun to give her a gigantic angry flying shark instead?

ScrumbleShip is an in-progress sandbox-style game of ship construction and combat simulation, all accomplished using a massive list of building materials and a surprisingly smart heat simulation model. Built around simple block placements, you have complete freedom of movement in this game, allowing you to jet yourself in any direction so you can construct the most accurate (or most hilariously inaccurate) piece of space-faring machinery you've ever seen. Want a tiny escape pod all your own? Done. How about a massive star base? Orbital station? Or maybe even a Death Sta— er, moon?!

Just over two years ago from this day, a relatively unknown indie programmer called Notch posted about a work-in-progress version of a sandbox building game on the TIGSource forums. It was called Minecraft, and at the time, people thought it was really very cool. Fast forward to the present and Minecraft has sold over four million copies, been through extended alpha and beta phases, spawned the Mojang indie studio, and gained so much popularity, the launch of its official version took place at a Las Vegas convention dubbed MineCon. That's an impressive feat for any game, let alone one started by a single person. But now, Minecraft is officially out. No more beta, no more alpha, it's here. Time to lose yourself in a voxel world all over again!

Terraria, a new action/adventure/creativity game from Re-Logic, is perfect for a sand emperor like myself. It offers the thrill of discovery mixed with the chance to meticulously construct your own little village, city or empire. And before you think it: yes, it's a lot like Minecraft, only in 2D!

Following in the tradition of the classic sandbox games (Sand Sand Sand and Powder Game), The Powder Toy by HardWIRED is a small download which stretches the boundaries of what is possible with a few simple elements. In fact, you can do almost anything with it, the only limit is your imagination.
