the nanos I PERSONALLY don’t care much for and I emphasize that because I find them too simple and very similar across all the different variants. Their main appeal is that they have so many with popular characters and yay cute wow but the actual like Creature Raising element that I enjoy it’s fairly light on. There is usually one or two “secret” characters that do require a bit more oomph but it doesn’t expect a whole lot of you in terms of how often you need to feed or play minigames. it can however also double as a cute/stylish timepiece accessory
basically what it boils down to is the sort of things your brother likes. just trying to figure out how to get every character can be the main draw
