I had Worms United (I think it was called) which was basically an expansion to the original DOS game that allowed for custom levels and SFX.

I created some worms sound packs loosely based on some of the pop songs on that era.

Fun times.

I never quite got into the later Worms games. Visually they looked great and the controls felt similar, but it was all a bit too cartoonish for my liking. However that might just have been because I was used to the original DOS games. But even now, I still crave that pixel art aesthetic in games (not just Worms).
