Some people out there are getting super nitpicky about Demon's Souls ("it belongs in a museum!"), but I'm more concerned about how it feels than any model or lighting changes. It looks so freaking good even if it's not 100% faithful to the original art direction. I just hope it plays well too.
Replying 16 days later, but I really dig that they're seemingly going for a more natural ambiance.
As in, instead of just a sepia filter shader or something, they're letting the actual designs of the environments speak for themselves. (If that makes any sense.) The PS3 wasn't capable of having too much detail in the environment as compared to the PS4 and PS5, so I imagine the filters really were more of a low-cost solution for adding ambiance to the worlds.
Look at the difference between them walls. Mmm. They're both full of ambiance but achieved in different manners. I think the remake is going to be more than fine.
