FAQ

Frequently Asked Questions

What does MMO mean?

In short, MMO stands for "Massively Multiplayer Online Games". While not a game genre in and of itself, the term is often used to describe any game that contains those three elements. If the game is played online, is a multiplayer game, and caters to a "massively" sized crowed (obviously a subjective term) then the game will often be described as an "MMO".

Often, MMO can be used to mean MMORPG, a specific type of MMO game. Guild Wars 2 and Eve Online are examples of MMORPGs, Destiny 2 and PlanetSide 2 are examples of MMOFPS games, and games like League of Legends or Fortnite may often be described as "MMO" since they do provide access to massive player numbers, but technically these types of games would better be described by other genre terms like MOBA or Battle Royale, respectively.

Since the term "MMO" isn't very specific by itself, the following games could all be considered by some to be free-to-play "MMO games" and are generally more popular now. Again, these titles are from many genres so if you are looking for something a bit more specific, try searching our subcategories instead. Some good recommendations though, in no order, are:

1. Path of Exile
2. Warframe
3. Destiny 2
4. Lost Ark
5. Guild Wars 2

It's subjective to say which are the top 5 MMO games as it depends on personal preference. However, some popular MMO games that have a large player base include:

1 - Guild Wars 2
2 - Destiny 2
3 - Warframe
4 - Lost Ark
5 - Path of Exile
