I think it’s more about the individual users you find in each of the duplicates. It’s like old forums. There would be several different sites hosting their own forums with plenty of duplicated topics, but you would choose one based on who was there. Multiple small options makes it easier to find the place where you fit in and can actually make friends instead of having fleeting interactions with strangers with whom you’ll probably never speak again.
Golden Sun and its sequel, Golden Sun: The Lost Age. Easily my two GBA favourites.
