I thought artstyle and look wise Outer Worlds was great. Nothing I can complain about there. PoE1&2 looked phenomenal as well IMO.
I think it's a bit odd to complain about Obsidian game's look when they mostly build campaigns for other people's games. KOTOR2 is just as ugly as KOTOR1. F:NV as F:3. NVN2 as most games build on Aurora Engine (perhaps Jade Empire is an exception).
The complaint I often hear regarding Obsidian is them making characters instead of wifus, but that's less looks and more priority thing.
Oh, I wasn't complaining about it at all. I think they got the look and general vibe of the thing exactly right. There was something quite special seeing the lumpen shape of the Unreliable careering into a rather pretty night sky, the silhouettes of the cliffs and trees nicely framing the ringed planet in the distance.
I thought the characters looked okay too. I mean they looked individual and realistic so no complaints there. I did feel a bit sorry for the guy with the moon hat though.
