This is a minor suggestion, but it would be nice to have some sort of option to vary the client's FOV angle.
As it is, the current field of view feels a little bit small, like looking at the world through a magnifying glass.
That's all I've got for now, though... So far, this game is headed towards just about everything I've ever wanted in an open-world sandbox.
Given time, publicity, and continuous support from the devs, this game has the fundamental potential to set a new benchmark for this genre if executed correctly. Keep up the hard work, and you might really be on to something big.
