i only use the galleries for when i feel like i missed a scene or variation of it, and when i found the game to be too tedious to do a replay just to see scenes that can only be scene through branches ive no interest in playing.
Heavily depends on the game. There are some games that I play that it's actually more worth it to just replay the game for the experience than just watching the clips.
Then there are other games that I play for a little bit and then decide to try the universal gallery unlocker on because I just want to get to the good parts.
I rarely visit galleries in games, but on the other hand when a game has "repeatable" scenes I tend to go back to them quite a lot. Idk why the difference, but somehow I find it more enjoyable
Pretty rarely. If I was to revisit a game, it's because I've deleted it and started with a fresh save. For me the story is important to ramp up the tension and feeling in a scene. It's just too different when you look at the gallery vs being hyped up by the story.
I routinely clean out my "games" folder so I usually get a mod, but I'd say certain games I redownload just for a particular scene / kink. Games have a way of being more directed than comics with similar kinks.
