What?!? You don't like meeting a LI, they instantly fall in love with MC, and then you toss them onto the ever growing pile of other LIs that are all perfectly happy to share or never be seen by the MC again? That's heresy!You might not believe it, but for me that is a plus! A big one actually, harems are to ... boring?!
All kidding aside, I fully agree with you. I personally prefer this style of game, as the LI's have to be written strong enough that they can keep me hooked throughout the story. Sure they do follow the basic tropes, but the ones I really like are the ones that add a new angle or facet to the trope to make it feel more unique. What some see as boring repetition, to me is replayability. Many harem-based games that I've seen create LI's following the basic tropes but don't add really anything unique to them.
