I guess, at least so far, that most had their first version played on a computer with a mouse, easily best way for a new player to get into it I think
. I did prefer a joypad for a time when was on the Mega Drive as I found it easier to control though. Bet these days that would be rare for a kid to need practice with a mouse.
Started with the black & white Mac version back in 1991. As I was a child at the time, it was a couple of years before I reached Pea Soup (Mayhem 14) and found that the level is nearly impossible on that version since the "peas" are invisible. I didn't think of trial-and-erroring through it because the idea of invisible terrain never really occurred to me... fortunately, with technology moving on, my dad passed down to me his Mac LCIII soon after. I was able to progress, but The Steel Mines of Kessel (Mayhem 26) is much harder than intended on the Mac version, and I didn't solve it for another ten years.
My friends and school computers mostly had the Acorn Archimedes version, so that was the other version I became familiar with. I didn't understand that different versions had different levels until years later when I joined the forum that was a precursor to this one.
Invisible peas? Oh wow, quite an oversight... Could've been missed in testing? Only fix I can think of is to have square peas,would look weird but it'd have been solvable. I thought only the Mega Drive one would have different levels because they're smaller. Till I had a look around other versions on emulators I never realised how many unique levels there were, it's quite surprising how many are only on specific ports of the game.
I'm proud and grateful to be able to say that my parents bought us an Amiga 500+ back in 1991 (when I was just 7 years old). We had the Cartoon Classics pack with Lemmings, Captain Planet and the Planeteers and The Simpsons: Bart Vs. The Space Mutants bundled with it (as well as Deluxe Paint III, which was bundled with all A500s, I believe - this is the very program upon which the Lemmings graphics were originally created!)
My and my brother and sister spent many a happy hour playing our Amiga - it didn't occur to me until years later that we were the original "PC gamers", whilst everyone else seemed to have Nintendo or SEGA consoles!
And, one game which of course I loved playing was Lemmings, with the "tank" mouse (a very uncomfortable but nonetheless iconic contraption which regularly needed to be de-fluffed so that the trackball would operate properly!):
I guess looking back it was similar for me for a while. Other kids would have Mega Drive/Snes, then there's me who mainly was on Atari ST, don't think I knew anyone else who had one, or an Amiga. Trying to debate whether that mouse is better or worse than the Amiga one. Either way much prefer a modern mouse to one of these gray blocks from back in the day.
Ever since my big Lemmings phase when I was younger which kind of petered out after the PS1 version of Lemmings 3d, I have been in and out of Lemmings games, did tend to dot around from versions so alot of my memories of when I first did X levels is a bit fuzzy sadly. I also loved playing ONML, and Lemmings 2 - the latter when I was bored was great fun to mess around on the Practice mode, my brother loved doing that too.
But aside from stumbles when I was learning the game still, think my first major hurdle was "If only they could fly", the Tricky version of "We All Fall Down", and I am sure I solved "Steel Works" before I could the 1st level of Taxing - the time limit on it is quite stressful.. Will have to play some of the other games again, ever since i discovered custom levels I think more of my time has been on those than the original games.
