I ran in the same homebrew that I created at age 17 shortly after 2E came out until 2009 and even played in a game set in that world run by a friend until 2016.
After a break from D&D and coming back for 5E, rather than try to convert that world again, I decided to make a bottom up setting (rather than top down as the previous had been) and knowing that published setting are not for me except for what I can steal and change. So I took a place from the old setting I had hardly used and that was a good fit for the Ghosts of Saltmarsh adventures (which I had run in their 1E incarnations using 2E rules back in late 80s and early 90s), changed some names, drew a new map and went for it.
I am considering running a Krynn-based War of the Lance game next but while I will buy the new 5E stuff, as usual I will homebrew and adapt my own version of Krynn based on my take on the novels and olde material I still have.
