Two I really enjoy are Index Card RPG by Runehammer, d20 done nice and light.

The other is Breathless by Fari Games, it has a free SRD and tons of games for it released under the Breathless Jam https://itch.io/jam/breathless-jam/entries

I have played the Shire adventures using the 5e version of TOR (LOTR RPG) and they are very good adventures. I also have all the old Adventures in Middle Earth books we played for 2 years using AiME sourcebooks. The adventures and source books are excellent for both lines.

Nice work, always handy to have another resource…and a good use of AI Chat doing the summaries.
