Judging by this thread a number of people are beating this "90-hour epic" in 15 hours. So I'm afraid I have to press X to doubt your claims that solving cases requires transcendent intellectual effort and intense concentration.
"Finishing" !== "beating." I'm sure you can
finish the game in 15 hours. I'm less sure that you'll be able to finger the right suspect with a solid case.
But, anyway, keep playing. Unless of course the inner dialogue wears you out first -- this is definitely not a game for everybody, and in fact I'm shocked at how many people
do get it.
I think your main issue right now might be that you've been so determined to hate this for weeks on end that deciding not to would be a bit embarrassing, so you're likely actively looking for reasons to hate it. Which is a fine Codexian tradition that I under no circumstances hold against you. This place needs
some contrarians and since the usual suspects have decided to join the cult, it might as well be you. Somebody else could get it wrong.
