Slowly built up romances in RPGs are fairly common, and sometimes well done. You have character attachment and similar ideals leading to the gaming version of a perceived "relationship." This current iteration over oversexualized nonsense that comes out of nowhere comes across as very poor writing and childishly immature. Modern gamers looking for everything to be a waifu sex doll simulator is quite honestly disturbing on some levels.
Most classic RPG players want choices and actions over time that resonate between characters, not a Harem anime. It is tacky.
