Unreal Engine had some deceptive AAA games on Switch (as a fan of Crash, the 1-2 frame latency of the trilogy and the huge loading times of CTR really kills me).
But it looks like Nintendo is doing great games with it. I didn't know Yoshi's Crafted World use UE too.
I enjoyed Pikmin 1 (GameCube) and 3 Deluxe, yet didn't really wanted to buy this Pikmin 4. But the removal of the timer (I know, some really love the timer, but I like smooth exploration) and the emphasis made to exploration and gathering things make me considering it.
