I loved Lemmings.

'Twas really cute and relaxing.

But I did not like Lemmings 3D at all.
Like Psychotic, I liked Lemmings: The Tribes as well. And also, like him, I wouldn't really save them so much as having them do fun activities instead of going to the goal like they were supposed to. Other times I'd make them blow up/commit suicide somehow (but that was back when I didn't have a heart).

That game and The Lost Vikings are probably my favorite games of that type.
