Project Spark Out Now and it's FREE!

The world and game-building sandbox Project Spark is out now, following a long spell in beta. It’s a free-to-play experience on Xbox One and Windows 8.1, with packs and in-game currency allowing players to buy more tools and content.

“Project Spark is an experience like no other that aims to democratize game making by giving everyone easy-to-use tools to create, play and share their own creations with others,” explains Microsoft.

“You can instantly play tens of thousands of user-made games, remix a pre-made game, or hop right in and make your own game with tools including 3D sculpting and a visual programming language similar to what the pros use, made accessible to all.”

Microsoft continues, “Fans will see a host of new content available on launch day including sci-fi skin, adventure mode, champion features, creation enhancements, and multiplayer mode to inspire all new gameplay.”

Alternatively, a Project Spark Starter Pack retail disc is also available. It costs $39.99 and includes $85 worth of downloadable content, including:

Champions Quest: Void Storm adventure
First Contact sci-fi theme pack
Sir Haakon the Knight playable champion
Arctic Glaciers winter landscape
Massive World Builders Pack expansion
Yeti’s Rage content pack
One month Spark Premium membership

I don't think i'd actually have the patience to create my own games, but it might be fun to play some of the other user created games.
