So far it's been alright, barring some ups and downs with performance.
Visually it's stunning, and the lighting is something else. I hope a lot more open world games have lighting as good as this going forward, and decent colour grading as well (hardly run into colour banding issues at all). That said I'm hoping we'll get some perf fixes in the coming weeks/months, because I want to take more shots with the game's photo mode (Starting to become addictive).
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
