Wow, well done then. But have you completed FTL with all ships on hard? Not saying I have but ummm, seems you’re not done with it! Not to mention, is that an achievement I see still locked!? 
Another one I’ve thought of: because you bounced off Civ Vi, doesn’t mean you won’t ever get in to it, it’s a fantastic game, so maybe give it a re-try some other day. Try and watch some starting guides by Quill18 on YouTube.
Nonetheless, have you checked out Through The Ages? It’s a board game, but it distils Civilization down to the very best of its essence. Games are played in about 1/6th the time, and much easier to track and the app is very well implemented. It’s initially a little obscure to get the happiness/population and production/corruption thing but once you do, and get familiar with it, the Civ world in card form opens up. Check it out. There’s also plenty of other board games you could consider, many with loads or if not endless replay ability. Race for the Galaxy is one. Tight game, great theme, games take only 15-20 minutes and are super tight and thought provoking.
Also, how bout desktop dungeons? Dream Quest? Card Quest?
And I also support the calls for darkest dungeon, Templar Battleforce, and cultist simulator.
Btw great selection for that deserted island. Because of those, my Dream is to someday get left on a deserted island lol.
Cultist Simulator as yet untouched. 
However, it wasn’t on my list because that’s another game I’ve thoroughly mainlined.
