Lilim Union: The Succubus Realm

For a game from 2013, Lilim Union aged surprisingly well (especially compared to other Tsukinomizu games). Gameplay is a typical exploration-adventure. The main gimmick is the time/date system affecting which NPCs/areas/quests are available. I found it pretty fun, from sheer novelty if nothing else. You have a limited ability to fast-forward through the week, so I didn't have any issues, but I can also see it getting old pretty quickly. There are no random encounters, a lot of shortcuts for map traversal. The music in this one is also quite good, they even played around with effects, like town theme getting a bit muted indoors, or a sound getting quieter when you move away from the room it's coming from. The story is, typical of the developer, a comedy adventure. It's good, but by its nature it's hard to really say much about it. I could praise the worldbuilding, but I also played like, 9 or 10 other games in the same setting, so I'm biased in this regard. Combat is streamlined, every fight being a 1 on 1. It's...not actually particularly amazing, but it is very fast, there isn't any party juggling, and equipment is more curated. Scenes are good. I think they were more censored than usual, but there's a good variety (as long as you're into tentacles and futa) and they are well done.
