Old School RuneScape

Price: Free (with paid subscription options)

This wouldn't be a proper MMO game selection without us mentioning RuneScape. The old-school version of this all-time classic has only recently been released on Android and iOS. What's even better is the fact that you can play cross-platform. Whether you play on mobile or desktop, you’ll be playing on the same account on the same game worlds.

As is the trend with most mobile titles, RuneScape is a free-to-play game, but there's also a subscription plan that nets you a bigger world map, eight extra skills, more quests, and other bells and whistles not available in the free tier.

Order & Chaos 2

Price: Free (with IAP)

Gameloft's Order & Chaos series are some of the most popular MMO games on both mobile platforms and for a good reason. The first game has served as an example of how to make mobile MMOs since its release, and its successor manages to take everything the first did well, and build on top of it.

The game features an extremely large and immersive world in addition to beautifully designed graphics, 5 races and 5 different classes to choose from, and all the necessities for a full fantasy MMO experience. If you're going to play one MMO on your smartphone, Order & Chaos 2 is definitely worth considering.

Dungeon Hunter 5

Price: Free (with IAP)

The Dungeon Hunter franchise is pretty popular in the mobile gaming world. However, in case you haven't heard of it, let us introduce you to one of the most popular hack'n'slash titles to ever hit smartphones.

Dungeon Hunter 5 is not an MMO game in the classic sense of the word. Instead, it relies on co-op and asynchronous multiplayer, akin to other mobile titles such as Clash of Clans. During the singleplayer campaign, you acquire different assets to place in your own dungeon for other players to raid. Your dungeon also includes an AI-controlled version of your own character, so if you've developed your base and character well enough, you might just fend off other players and protect your gold.

Other than that, the Dungeon Hunger 5 plays a lot like a classic hack'n'slash with polished graphics and pretty entertaining gameplay mechanics.

Toram Online

Price: Free (with IAP)

If you're into anime, Toram Online will definitely not disappoint. The different art style is far from the only thing that sets this game apart from the typical mobile MMO. First off, we have to say that Toram Online offers an incredible a mount of customization options, so if you're the type of person that loves to have a unique character, you'll definitely appreciate all the cosmetic stuff crammed into this title.

The flexibility of Toram Online doesn't end there - the game features a classless system where you can create your own custom build and style of play by combining different skills, stat attributes, and weapon types. Last but not least, the storyline is filled with cutscenes and interesting dialogue, making it quite immersive.

Rucoy Online

Price: Free (with IAP)

Last off, we have an interesting indie proposition. Rucoy Online might not feature the stunning graphics of HIT or Lineage 2, but it can definitely be charming for nostalgia buffs that yearn for playing something like the SNES version of Legend of Zelda. The combat mechanic is pretty straightforward - you just tap on anything that you want to kill or interact with. In addition to that, you have your standard leveling, skill, and loot systems. What's interesting about this game is that you can instantly switch between the three available classes - Knight, Archer, and Mage. Sadly, Rucoy Online isn't available on iOS at the moment.
