anyone up for a quick session tomorrow night (Tuesday 20~21:00)?

For Lemmings Plus I have you ever tried Lemmings Plus I or II? I think those are the easiest packs and even Omega I might be manageable by you. Definitely packs like Omega II might have to wait until after Reunion to conquer according to your explanations

LPO isn't much harder than LPI or LPII. It felt hard at the time because it was the first major pack (and second pack full stop, after the very easy Holiday Lemmings Plus) to make use of the new skills. By today's standards, where most players are used to the new skills, LPO should be no harder than LPI or LPII overall (although I must admit Mental 29 is nastier than anything in the other two, except maybe Death Row).

No problem, Nepster, don't rush it! The longer it takes to get the shimmier working, the more time I have for converting Lemmings World Tour - I don't want to fix backroutes in both format versions separately...

But with your ranking in mind, I think I'll make my list as following:
- finish Lemmings Squared
- GeoffLems
- MobiLems and/or DoveLems
- then PimoLems
- after that, possibly Lemmings Reunion

I think this sounds like a solid plan. GeoffLems is indeed a great pack, and it is a very traditional type of pack with classic skills, repeats, and levels that start out easy with 20-of-everything... but don't let that fool you for the levels get much harder towards the end. There was even one level that I didn't solve until months after finishing the pack!!

MobiLems is also great and I think it is on par with GeoffLems in terms of difficulty. DoveLems I would say is a bit harder than the previous two I mentioned, although honestly I think that some final rank levels aren't as bad as some of the third rank levels and this is probably because of NeoLemmix in some cases. There are a lot of trick orientated levels as well and they are pretty good at blowing your mind.

PimoLems I'm still not 100% sure about since I haven't officially sat down and went through it on my own yet, but people have said that it starts off very easy and gets quite challenging in the end. The final rank is harder than those from DoveLems, MobiLems, and even GeoffLems.

Reunion I have started off and on and it gets quite tricky already in the 2nd rank but it's also great and I wouldn't let the difficulty of it put you off.

Other packs include Clammings which starts off easy but gets quite nasty towards the end. Deceit's Lemmings also gets challenging at the end but I would say the final rank of Clammings is a bit harder than the final rank of Deceit's Lemmings at times (although some people might disagree especially if you consider the infamous Mayhem 21 from Deceit's Lemmings)

We've already discussions about "What makes a level fun?", but this, I think, is still a little different. A level can be fun without being particularly challenging or tight on resources ("resources" includes time and lemming count itself here). That's kind of what happens while you're playing the level; I'm talking about the moment right after the level.

For me, this pretty much comes down to "I don't like having excess skills" . Nothing is more rewarding in my view than using the last skill on the panel in any given level and seeing how the path is completed and everything has fallen into place. That's kind of the idea of the "puzzle", isn't it?

Who would want a puzzle where, after completing the entire picture, you still had some leftover pieces? What's the use in finding the corner stones first if there are additional corner stones so that you don't need to use these particular ones? Why should there be a crossword riddle where you'd have some extra words remaining unused at the end, or some rows empty?

The main reason for my repeatedly uttered grievances with 10-of-everything levels therefore is not the level type per se - but the fact that this type of level produces excess skills more than others. This, in turn, also explains my obsession with Final Frustration-style levels - because here, everything has to fall into place despite the seemingly "open" nature of the level.

The result is that I like to make my own levels as tight on resources as possible (where time is the resource I use least): You usually have to save everyone, and if not, those you may lose are exactly accounted for (including cloners, I've learned after Pit Lems !). And you usually have to use every skill, except perhaps when there are certain gaps which cannot be bridged by a specific number of constructive skills. In that case, there may be an occasional leftover builder or platformer. But I always try to avoid it.

So perhaps I should give designing Lemmings 2: The Tribes levels a try some time in the future (because these are usually "save everyone" levels)?
