I'm still amazed that there was ever any controversy about that level - I never even heard of the faintest hint of it until I found The Complete History of Lemmings... Then again, as those writings themselves attest to, the UK is a secular country, so it's unsurprising that I never knew of it myself until reading about it all these years later.
Heh. I remember when I was about 5 or so, playing that level (well, the PC version, so "All The 6's" I'm meaning here), my grandparents said they really didn't like me playing that one and suggested I should play a different level instead. Their knowledge of the concept of having to pass one level to get to the next was about equal to my knowledge of why there was anything "wrong" with that level, there again, they are the obsessive religious type.
Earlier today, I played the PC (well, Amiga really) versions of the special levels' replacements. I knew they had more restrictive stats/skills than the Master System ones (especially Taxing 15), but I didn't expect them to be as hard as they were. Still not too hard, but still, far more than I expected. I actually reckon Mayhem 22 was the easiest of them.
On Sega, I always found Tricky 14 to be the hardest of the four by far, whereas on these versions I'd say Taxing 15 is harder... I'm fairly sure my solution was a backroute.
EDIT: Okay, the differences between the PC version and Sega version graphic sets would make remaking Sixes Not either overly difficult or not play much like the original, so I think I'm going to skip that one... xD Or I could maybe do it as a VGASPEC... in fact, yeah, I like that idea. (EDIT: DONE! It's not perfect color-wise, but it'll do - I had to change the white to a red because otherwise the lava along the bottom looked plain awful.)
EDIT: Sega Five isn't far off either (guess you were right, Prob Lem
). I've done all the major parts of it; just got to add the pipes, huge SEGA texts and the grass lumps. And set the stats. So goddamn fiddly with all those little platforms; I'm glad it's the *only* Sega level that's like it is. xD
