My only regret is the game is not designed for the player still roaming the world and finishing various quests after the main story ends, like in the various Marios. If you want to keep playing, you have to keep Ganon alive and get the regular Blood Moon reminder here and there.

That's always how I've played games. Once I see the ending the game is "done" and I can't get myself to play it anymore, so I always do the final boss last

This is the exact reason why I haven't killed Ganon yet, in spite of putting 400+ hours into the game. Now I look forward to starting all over again - this time in 4K and with hopefully better performance, once I get my Switch 2.
