Just started and it seems great. Kinda disappointed that the starting background doesn't seem to matter as much as I believed it would (so far). A little buggy but still very playable. Combat is good, not great. Driving is a little wonky. Still has a great aesthetic and I'm looking forward to playing through the main story.
UPDATE: now that I've had a chance to play a bit more I've got to say I'm disappointed in how laggy and glitchy this game is on XBOne. It's crashed on me several times now. I'm surprised that my saves haven't suffered (so far) and it seems like there are enough checkpoints that you can get back to where you were fairly easily. It just makes the game MUCH less playable than I'd like. Still think it's a great game as far as art, script, concept, etc. Just wish it was good from a technology standpoint.
