True, we haven’t. It’s mainly M’s route (my favorite one of the four) that I find irritating that way. I mean, A is a bit of a tween angst machine himself, so having the MC be just as bad makes sense. And N is your typical RO from the old “gloved hand touch is scandalous” romance books. F is different, and fun. But M is supposed to be all about boning and is completely hostile to the idea of any emotions–I just want the same for my MC, and not to feel like she’s forced into falling in love with someone who wouldn’t piss on her if she was on fire (unless it would get him laid
).
That was actually my point. There is no separation between sexual confidence and emotional constipation. So far, I have yet to see a game that actually does separate the two. TSS gives the player the option to have their MC pursued (with A, at least–if they’re waiting on R to pursue, they may as well give it up, but that makes sense for the characters), and it feels like it was meant more for adults. TWC is great, but it does have more of a tween feel, with the ROs as well as the NPCs. Book 2 may change that, but right now, that’s the impression I have.
Nope, no killing.
I am curious, though–how does TWC work better for ace? Is it the shyness? Just curious, so don’t feel pressured to answer if you aren’t comfortable with it!
For TSS, I think Cara did a great job at giving the option for calm. My MC was pretty chill about the whole thing and I didn’t feel like she was forced into being otherwise. In TWC, I feel like MCs are forced to be… nice? Even when they aren’t “people” people (my main MC has 1% in people, if that tells you anything!), they don’t get real options to respond in kind to other characters’ BS (like M, I want an option to be just as rude and nasty to him!). With Rebecca (don’t kill me for this!), the MC has no real option to be hostile toward her, just mildly resistant. My MC hates her and wants nothing to do with her, but the best she can do is flinch away when the woman tries to touch her.
Getting off topic here, but wanted to respond to that. 
I agree about Soul Stone War! I can’t wait to get that one. I have a feeling that the romance there (back on topic, yay!) might approach what the OP was talking about. Morkai and DaeDae are far from shy and definitely pursue the MC, which is so freaking awesome.
Edited to add:
If you haven’t checked it out, take a look at Supernatural in New York. I don’t know about other paths, but the path with Grey actually gives the player a chance to “choose” how Grey responds in one point, making him the pursuer. It’s not exactly what we were talking about here, but I like it and it works really well.
