Can somebody answer me why this game doesn't have a gallery mod? it seems to me like a game that needs one.
Can't say what is on the devs minds, but I can easily think of several very valid potential reasons:
1. Most scenes are repeatable anyway and simply require going to the place at the right time. This makes developing a gallery mod of much less value for players, and thus for devs to waste time on compared to the value of spending the same time on new scenes and content.
2. There is already the dream mechanic and system that fulfils the basic function mod, and seems (to me) to focus on the non-repeatable scenes. See point 1.
3. Given the repeatable scenes and dream system, what little use or value there is for a gallery mod is mainly for people to be able to see all the scenes without playing the game. The devs want people to play the game, obviously, or they'd just make a CG set.
4. There may be plans to create further scene gallery systems before the game is complete, but due to the limited value right now, and the much higher value of progressing the project as a whole (new scenes and content) it is a low value item on the 'To do' list, and likely to be in the 'polishing' phase after the game is basically complete.
