Yeah it seems easy enough to imagine how much work it would take to add NPC schedules to a game that doesn't have them already. The Day/Night cycle visually not affecting gameplay, to me seems reasonable though.
One stated they weren't happy with PoEt's cycle because it was only visual, but I liked it vs always one way. I get NPC schedules for open world games that are going for realism, but this isn't open world.
Something I'd like to see is 4x map sizes, the larger the maps, the more I feel I'm not in a square and that I'm in a living world with some real treasure hunting going on. Is there any word that the game canvas's maybe larger? And that is something that bothered me with PoEt, their map sizes were no larger than BG's and the load times were slower than BG. This is 15 years later on massive systems compared to then. D:OS was still well larger in size and had no problems with load/save times, but put me in for being ok with even larger area's to run around in without loading a new map.
