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.
Total recall was my first thought as well. But I’m sure there’s got to be worse ones than that.
Probably the LJN’s entire NES-catalogue? IIRC they were pretty much all some media-property-license-schlock.
