As for my own history with D&D:
I started playing when I was 17, in 1982; I’ve extensively played all five of the “main” versions of the game (not counting the D&D games, which were distinct from AD&D, in the '80s).
2E was probably the low point for me, as far as playing D&D; It wasn’t a particularly wonderful system (it was largely just an update and refinement of 1E), and it coincided with the period during which TSR was, to a certain extent, wandering in the wilderness, and was being run by people who weren’t gamers and didn’t love the game. I was, indeed, playing a lot of Magic: the Gathering back then, as well as other RPG systems (particularly West End Games’ Star Wars RPG).
3E/3.5 definitely brought me back into the D&D fold; soon after 3E came out, I got involved in the RPGA (TSR/WotC’s organized play organization of that era, which ran games at conventions and game stores). And, at that same time, WotC got the Star Wars RPG license, and created a d20 Star Wars game – so, between D&D, and Star Wars, I was playing a ton of 3.5 and d20 from 2000 through 2008.
And, then, 4E came out. It truly felt like a different game (because it was), and while D&D has always been on the “crunchy” side, rules-wise, 4E took it to another level. I played a lot of 4E for a couple of years, but got burned out on it – largely because I came to realize that the rules were so complex, and made the players (and DM) keep track of so many effects and durations, that the system was actually making it harder to enjoy other aspects of the game, like story and role-playing.
The breaking point, for me, was around 2012 or so, when I was DMing a 4E game for one of my gaming groups, and I was trying to describe a scene — and I realized that none of the six players at my table were paying any attention to me, because they were all face-down in their character sheets, studying the various bits of rules about their characters’ abilities.
That was when I (and my groups) started playing more Pathfinder, and largely abandoned 4E. At that same time, I also started exploring other game systems, and started to fall in love with systems that were less crunchy, and (IMO) did a better job of encouraging collaborative storytelling and roleplaying – Fate, in particular, became my RPG system of choice for GMing.
I played a bit of 5E when it first came out, and then didn’t touch it for a couple of years. At about that same time, I was also playing less Pathfinder, again because my tolerance for rules crunch (and the ensuing debates and fiddliness that dominate play with a crunchy system) has really decreased over the last decade.
About four years ago, one of the members of one of my groups volunteered to run a 5E game for us. We’re still playing that campaign (though mostly over Discord and/or Roll20, due to travel issues and COVID), and while I adore my character (a bard), I find that I quickly tire of rules debates during games, and having to keep track of those fiddly bits.
While I’d agree that 5E is not as complex as 3.5 (much less 4E), it’s still more complex than I prefer these days. Also, many of the published adventures (which is what our group has been playing) tend towards old-school “dungeon crawls,” and those don’t fit well with how I like to play these days, either.
But, even if 5E isn’t a good fit for me, I have to say that I’m thrilled at how well D&D has recovered from the 4E experiment, and just how mainstream D&D, and other RPGs, have become.
