I have to say that I like this game A LOT more than "Good Girl Gone Bad". GGGB had a lot of sex, drugs and especially fetishes, which is good for a quick fap and that's why a lot of us play those kind of games I guess, but I didn't really care about any character, i just wanted to see them fuck and get wasted.
However in this game I am actually invested in it, probably also because you play both sides of this relationship and both aren't complete assholes, dummies or sluts. There are nuances, but all of them are just like that, nuances, though I suspect you will be able to reinforce this or that later on. Overall all the characters are way more believable and just likeable, except for the obvious jerks.
"Our Red String" is much more slow paced, especially if you want IanxLena to happen and don't want to fuck around elsewhere, but it is astonishingly cute, healthy, rewarding and just wholesome I have to say. I want to see their relationship to grow and not just to fuck each others brain out, which is still a plus, but that's just the dessert after the actual meal I am looking forward to. I want to see how this plays out, the sex is just a nice addition to it, part of this relationship and not the core of it.
Nonetheless I wouldn't mind, if there was an option to get IanxHollyxLena to work out, as all three seem to be into each other and honestly that would be just even more wholesome in my opinion as all three seem to on the same level, be it intelligence, dreams, behaviour, diligence, modesty, care, support and love. I know, I know, monogamous realtionships and blah, I genuinely want to see them together and not just to fuck.
I only played until late chapter 3 so far, because I was actually reading and not just skipping around to see the nude scenes, so it took me quite some time and I can't really judge how the later chapters work out yet, maybe it all ends in a huge gangbang afterall, but I sincerely hope it doesn't, unless you as the player really want that.
I didn't think I would ever use the word "wholesome" in the context of an erotic game, but that's the best way to describe the game in my opinion (so far).
P.S.: I didn't really read much of this thread to avoid spoilers, because for once I actually care about that.
