Alright, so here's a very-very-very preliminary version. As in, don't consider it even close to final; it's really just a first attempt to compile together the probably-will-be-used levels.
It includes:
1. Original Lemmings (Amiga). All
unique, non-special-graphics levels, except for Tricky 28. In the case of levels that have repeats, the later (/latest, in the case of WAFD) version was used, except in six cases: Both versions are retained for Fun 2 / Tricky 18; Fun 4 / Mayhem 20; Fun 5 / Tricky 16; and Fun 7 / Tricky 19. In the case of Fun 18 / Taxing 19; and Fun 30 / Mayhem 24, the
earlier version has been retained.
2. Original Lemmings (Genesis). All
unique levels are retained, using the same rule of "later version in case of duplicates". The exceptions are (a) remakes of ONML levels, (b) "Stray Sheep" (similar reasoning to Tricky 28), and (c) the extra special graphics levels. However, the Genesis versions of the also-found-in-other-ports special graphics levels
have been retained.
3. Original Lemmings (Master System). The
earlier versions of the 5 Sega levels are retained.
4. Original Lemmings (other versions). Added all the levels found in the "Others" rank of the Extra Levels NXP, except "The Apple Computer Level". (Including Vacation in Gemland)
5. Oh No! More Lemmings!. Added all levels.
6. Prima and Covox. Added all levels except the two special graphics ones.
At the moment, the first 9 ranks are named after Orig / ONML ranks, which I like as a possible final structure. All levels have been grouped by the rank they were originally in (which will obviously not be the final structure); in the case of the two levels that don't really
have an original rank as such ("One Way To Freedom" and "Vacation In Gemland"), I used my own judgement as to where to put them (Taxing and Wild respectively), but this will probably change as the pack develops. To avoid having to make judgement-based decisions at this stage for a large number of levels, I simply added extra "Present" and "Sunsoft" ranks and put the respective levels in those for now.
https://www.dropbox.com/s/0jnt81iyxmwd0at/LemmingsRedux.nxpSo - no need to try and seriously play it at this stage, as the levels are unmodified from the versions found in other NXPs (apart from removing any use of oddtabling, and changing Genesis levels to use regular version graphic sets). It's just to see what levels have been included.
So the next part of discussion should be:
1. Should any of the removed levels in fact be added back in? If so, why? In the case of duplicates, should the retained version be swapped with the removed one, or should both be included (I would like to lean away from doing this as much as possible, but there are cases where it may be justified - there are four examples of this already; five if you count the two versions of Just A Minute from Mayhem).
2. Which further levels should be removed? I've essentially removed only on account of repeats, completely worthless levels (eg. The Apple Computer Level), and two levels that go against the "no hidden exits" guideline (although I didn't remove Taxing 17; we probably need more discussion around this one as it has perfectly-accessible visible exits as well as a hidden one). I have avoided removing, for now, even almost-universally-disliked levels like Taxing 14, though. In particular, what should we do about the special graphics levels, now that we don't have one per rank anyway (unless we make four extremely large ranks as the final structure)?
3. We also probably want to decide fairly soon about whether or not to include Holiday Lemmings. I'm leaning towards no.
