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.
Yeah, a single NES game was tough for a kid to save up for. I was usually able to do various chores around the neighborhood and be able to buy a game every few months. I distinctly remember that Zelda II was $52 and Metal Gear was $48 and I earned the money myself as a little kid. Those two games specifically were worth the effort. I’d have been pissed if I spent that hard earned money on Ghostbusters.
