Now that AC is finally going the way of the dinosaur, those fans are probably looking for a new game to call home. It looks like Project Gorgon could be considered for this role. The lead Dev team are a husband/wife duo that used to work on both AC projects. While this new game is not intended to be an AC3 in any way, it does seem to at least be something of a spiritual successor in some ways. It is in pre-alpha and free to jump in right now and take for a spin.
