Monster Galaxy Soft Launched
Monster Galaxy has been soft launched, and is available on the games page -- thanks to the Moga team for the great game!
There is some (understandable) confusion about the requirement for Facebook Connect. You do need to have an account on Facebook but you do not need to connect your Gaia account to Facebook if you don't want to -- just log into Facebook at the appropriate time and you'll be able to play.
Why the requirement to have a Facebook account? Simply because that's what the game was originally written for, and we wanted to get the game out earlier rather than later.
The only issue I have about the connect is when they said, "you DON'T need Gaia to connect Facebook." Because if we don't, then how the heck do we get our Daily Prize? :/

Well honestly, you don't need it. It is just nice to have, so you can play with out it. I have.
