2 is at least worth a playthrough if you liked 1 if only for 4th and 5th chapter. Ultra Despair Girls is pretty crap with the only good thing being the silly chatter between the two MCs. V3 I haven't yet played but it's supposed to be a giant middle finger to the fans, on top of being full NISA.

The original concept for the game was quite different and even darker, with "trust vs. distrust" instead of "hope vs. despair". The working title was even "Distrust", and there's a fair bit of info about that online. Beyond that all the games are NISA's handiwork but 1 got an OK translation, and supposedly better than the fan translation for the original on PSP. 2 gets worse. V3, as I said, is where it gets to NISA=CANCER levels.

Oh god no. Unless there's something in 3 the only pronoun shenanigans are a glitch in the first game where trying to access another character's room always says "looks like she's not there" even for the males. I tolerate the existence of the trap character since it's not a big mess of virtue signalling and actually serves to muddy one of the cases.
