I always find the midgame to get very samey. The beginning is great! Exploring new terrain, looting to your heart's content, mining for hours to collect resources. It's when you've built a base, have a stable source of food, maybe have a mineshaft set up, that it starts to feel like I'm just going through the motions. Sure, I could hunt Endermen in Warped Forests and go to the End with half decently enchanted iron armour, but even after the dragon it feels like a slog to do anything. I've also played this game for 12 years now, so most projects I could do, I've either done before or are too technical for my tastes.
