My kids started getting into one piece, an Anime I admittedly never watched, so I watch it with them. I get the hype now, there have been several times we’ve torn through 8+ episodes in one sitting. Skip Intro makes it fly by.

If playing in a video game and being stuck there counts as isekai, then Dr Stone getting teleportated to a future stone age world counts as an Isekai, and Dr. Stone is excellent.
