2nd edition was fantastic, it had the attack and save progressions in the PH similar to Moldvay so you could do a lot more with just the PH. My group pooled money and I preordered heavily discounted PHs out of a comic ad for everyone ($10 each I think) so we adopted them in quickly and continued with our 1e campaign with mostly 2e rules but 1e grugach, drow, and assassin PCs continuing fairly unchanged. The system was backwards compatible enough to mix and match modules and monsters and magic items interchangeably without problems. Fairly similar to the 3.0, d20M, 3.5, PF1 family.Are you a clone of myself?
I did everything you did. It took me a while to get into 2nd edition as it was not different enough but I too, took the demi-humans level limitations and apply them to my 1st edition games. We fully migrated to 2ed in 1994 (around)... We tried PF but it was too close to 3ed for us to play it fully. It had the same number bloating problems as 3.xed. 4ed brought a nice change and had great ideas but some of these were poorly presented and combat in high levels were taking forever. And yes, Keep on the Shadowfell came a bit late in the editon's life. It might have helped a lot (or not...).
4e relied heavily upon being the new D&D and ditched having any free SRD or intro rules packet type option for a long while to try to monetize everything and drive people to buy the physical books as the only option (eventually dropping 4e PDFs then all WotC PDF sales for years). I was happy with Pathfinder and the metric ton of d20 stuff I had so I was not screaming out for a new game/edition. Having a ton of older edition and current Pathfinder stuff plus SRDs for Pathfinder, and not having the free 4e base, it was years before I got into 4e. In contrast I had adopted 3.5 fairly quickly with the SRD and had bought many 3.5 books from the beginning of its cycle and then the same with Pathfinder. I eventually got into 4e when I joined a new group and really liked it but the hits kept coming with them switching the online service one month after I joined from purchasing a great set of stuff to own with monthly new stuff updates added to change to paying for temporary access only with no ownership. When my group decided everybody but me did not like the 4e system we went to Pathfinder 1e for years and I cancelled my 4e online service.
