5 Best and Most Played Massively Multiplayer Online (MMO) Games of 2021

Massively multiplayer online games, or more commonly known as MMO games, are one of the most persistent genres of video games. Whether it’s a detailed world, a massive player base that interacts and completes missions with each other, a functional economy that affects all players equally, MMO games create a complete ecosystem in the title.

MMO titles also usually have an ongoing lore that adds up to a persistent update cycle. MMO games generally have a subscription-based model rather than a pay-once-and-own-forever model of titles from other genres. However, there are quite a few exceptions.
