Absolutely, I always find it more of a challenge knowing how avoidable content is. I often like running solo monogamous routes in games, no harem, no threesomes, no sharing, no forced side girls. Have no problem with that content being in the game at all for those that want it, and a game having those tags, but want it all to be avoidable. It would be nice if there was an easier way to tell other than just asking on the thread, but not sure how you'd actually do it.
This game isn't perfect, but I do like that most things are optional so far. Sage is probably my favourite and it's fine that she has threesome content, but I'm really glad that you can avoid them! I'm assuming that it will stay that way going forward...
