I have to push back on that a bit.

I played through the campaign for Alien vs Predator for both the Space Marine and the Alien campaigns in BigPEmu, and I really think it's a mediocre-at-best Wolf 3D clone. If it had been released on anything besides the Jag, then I think it would be, at best, relegated to the annals of mediocrity like the dozens of other Wolfenstein 3D knock offs. I wanted to like it because I love the first two Alien movies, but I really do not think it holds up compared to most FPS games, even at the time.

I haven't fully gone through the Turbo CD catalog yet, but I did play through It Came From Outer space and that was a blast in a "so bad it's good" kind of way.
