The curious game wot makes games - Project Spark - is now open to. The title was shown off during the Microsoft E3 conference, where players sculpt their own open world environments.
They can then fill those creations with settlements and NPCs, before dabbling in some scripted quests and the like. The selling point is sharing these 'games' and even remixing.
Project Spark is for PC Windows 8, Xbox 360 and Xbox One with cross-platform play on the feature list. The only info about the game came from Microsoft's video presentation of it.
Below is a PR-overdosing trailer for Project Spark.
