Minecraft Dungeons: Cloudy Climb Adventure Pass

It's like a battle pass, you get xp from basically anything just in small amounts, completing weekly challenges grants more xp and you keep progressing post season, other reviews seem to think you just get everything or haven't relaunched their game. Very good and cheap, adds some more sense of progression.

You keep progressing even if the season is over. All rewards are still attainable.

Cosmetics such as enderling skin, static shock, etc. good for $4

You should buy this only if you really want the cosmetics.

This is similar than Fortnite but you get all the rewards faster
