I really appreciate the ability to have a good conversation about this with so many who care and are knowledgeble about the topic. If that means we use a thread for a game that's on life support for a better purpose, then I say we're improving things.
For me, Tacos is just a frustrating game. It feels like there's room for it to be better, or more of what I want, but its either just not there or its hard to find, wading through the options that I don't want. I sometimes cheat with the URM when I just can't understand what the right steps are to get to a scene that I notice might be lurking under the surface.
What I want is a situation where both the man and woman come to the realization that they are cool with an open relationship, which includes both swinging/swapping and both of them doing things on their own with others, but unless I just keep messing up, the best I can figure out with this one is letting her hook up with other guys (while the MC sometimes creeps on them), while he is able to sometimes cheat on her behind her back, and risk potential consequences for that. What I'd much rather have is an ability to work up to where the MC can go out and have his fun without needing to talk about it, while she does too and then recounts them in a story/flashback to him a little bit later, instead of the peeking and hiding in the closet. It would be so much sexier if instead of the MC sort of ordering her off to have sex with someone else, that she's more in control and is then seduced into more and more risque and raunchy action without him there watching.
