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.
In Baldur's Gate, especially in the cities, it made a lot of difference. Also plenty of night-only sidequests available.
Compared to that, in PoE in the night vendors don't even go away, all quest-NPC's remain (just random uninteresting civs get less), there's no night-specific quests. And the whole awesomely ONE(!) night-NPC is only a craptastic vendor.
So yeah, it was pretty hard for me not to be dissapointed in that.
