My main problem with about any of those three letter word games is that they are more or less the male protag version of all those badly done female protags centering about rape and blackmail. The women have no consistency of character and basically gameplay comes down to cockblocking others instead of having relations with the ladies yourself or throwing them to the wolves if you do not cockblock. Not much fun for me in those games.
My main problem with the 3-letter-category is mainly that people whine about it all the time, even when it actually doesn't apply and they incorrectly demand for that tag.
My second problem with the 3-letter-category is that, indeed, most of thosee games are terribly written. So, because of that tag, I probably miss out on a couple of awesome games where the tag actually doesn't even apply, because I'm suspecting a crappy game when it is actually a decent game that isn't 3-letter-category at all.
