For me, it has to be Alien: Colonial Marines as it’s terrible due to inconsistent frame rate (moments the game ran smooth and times where lag was insane, even with the best hardware). Both player & enemy AI is crap since the combat wasn’t even that immersive plus Xenomorph AI isn’t as intimidating due to it being poorly implemented.
I cant speak on that, haven’t done any deeper research in that matter, just the original funny fact got lodged in my brain and not like I’m ever going to test it out myself.
