I made a game online together with someone. Or rather started it with someone and mostly finished it alone, since the other couldn't put in so much time anymore because of his job . Working together online with screen sharing is fine, especially when the content you are sharing is digital anyway. You sure learn different ways of seeing things. You'll also have to accept things aren't always done your way.
With painter and sculptors co-living is commonplace. It's called artist residency. You'd have to apply with your work and it's not easy to get in. I think it's a matter of research to find an artist residency for digital artists or an artists residency that is willing to take in a digital artist (maybe hoping he'll fix all their computer issues).
