In any MMORPG, player-created factions are an indispensable part of the game, and even one of its main features.
Take guilds in games like "Legendary Journey," for example; if you're brothers, let's go hack and slash together! Or it could be a large online social platform where you can find brothers, girlfriends, have your brothers become girlfriends, or your girlfriends become brothers... such stories are far from uncommon.
In many cases, players might have grown tired of the game, but continue to play because their friends are still playing. It's less about playing the game, and more about playing with friends.
However, no matter which online game it is, establishing a player faction is quite simple. Either you'll meet the level requirement and gain the qualification to create one, or you'll complete a very easy quest to unlock guild features—online games don't tend to intentionally create obstacles here.
