Windborne
(Seth also played it but I thinK i prefer guude)
"Windborne brings social sandbox creation games to the next level. Explore a vibrant world filled with secrets to unlock and treasures to find, craft personalized furnishings and innovative artifacts, and befriend intriguing Jin to help build a new civilization. Will you seek out the clues and artifacts of the ancients, or just loot passing islands for minerals and rare plants? Bring along your friends while you play, and share your creations with the world. Where will the wind take you?"
In a way most of you can understand, it's like minecraft at the next level.
It's still in very very early alpha, so don't expect much. (even though you can't play) I have high hopes for it and what Guude said really interested me. There's villager creature things that guude was talking about that evolve as you evolve. It reminds me of the villager's from minecraft except they are way better like they are in the Millonaire mod.
It's made by the same guys as Age of Empires and CS:O so I expect great things.
