Some players may find themselves running out of things to do!
Whilst we can't give you all unique ideas per person, we can help you out with some places to find some.
You can always improve any redstone automatic farms, this can also be quite a large and fun project! Tutorials for various farms can be found with a quick YouTube search, you can even try designing your own if you're feeling adventurous.
Possibilities are endless for building in Minecraft, but sometimes we just can't find any ideas! Again we can't provide you all with unique ideas per person but we can suggest some places to look. The Minecraft subreddit often has some great builds that you can take inspiration from. Not everyone's a great builder but we all start somewhere, and nobody is judging you!
