Mabinogi
Mabinogi is a 3D MMORPG fantasy-themed game with cute, anime-style graphics. The game’s world is quite unique, combining the elements of social games and those of RPGs. There are an awful lot of things to master for a beginning player (the eccentric combat system; fishing minigames; cooking; and even composing music if you like), but Mabinogi has a very helpful community for a F2P game, and skills are easy to use once learned. You’ll especially like setting up campfires where you and fellow players can engage in lively conversations under the night sky. However, there are quite many paid features in this game: pets, character resets, and creating new characters costs Nexon gold.

MechWarrior Online
MechWarrior Online is a robot-fighting shooter MMO that follows the classic Mech Warrior series. Aside from the stellar graphics, players will be surprised by the sheer number of things they have to remember and take into account during combat. Players have to think about their mech’s heating, remaining ammo and also about the parts of the enemy mech they want to hit to gain an advantage. Four types of mechs make the gameplay quite diverse, but balancing issues sometimes cause games where the team with the better composition of mechs brutally dominates the other. Teamwork is the operative word: players have to communicate via the built-in voice chat or their team will get stomped over. The learning curve may scare beginning players, but as the game moves out of beta we’ll hopefully see desperately needed improvements in social features, matchmaking, and actually introducing the players to combat with a tutorial.

Might and Magic Heroes Online
Might and Magic Heroes Online (MMHO) is a 2.5D MMORPG/Strategy played in the browser. It�s developed by Ubisoft and features the original HOMM world of Ashan. MMHO has the player choose between two classes of two factions (so there are four classes altogether) and battle it out with NPC and player opponents in turn-based battles that demand quite some skill. Players have a hero and some basic units to start with and later on get a town for producing new types of units. Players progress fairly linearly, with quests introducing them to the various parts of the game. The greatly detailed world looks stunning and atmospheric, with some random loot lying around as well; however, the detail sometimes takes its toll on the UI, which responds slowly at times. MMHO is definitely a title worth trying; especially so if the desktop Heroes of Might & Magic games saw you ladder with your friends for weeks on end. The cash shop seems quite democratic as well, as you can really do without it if you�re not dead set to reach the top ranks on your server. Other than the lack of player customization and the clunky UI, there�s surprisingly little bad that can be said about this game.

Minecraft Classic
Minecraft Classic is a sandbox-building game developed by the Swedish game designer Markus “Notch” Persson. Mine resources to survive the things that go bump in the night, or focus on creating your own world. Almost everyone has heard of Minecraft, but its charm is hard to grasp without actually playing it. Minecraft gives players absolute freedom -- create your own imaginary structures and destroy them or show them to your friends for “Minecraft cred”. The full version, which supports the latest features and the official game server, must be purchased -- but the older Classic version is free, and lets you log in to any of a huge number of independent servers (or set up your own).

Ministry of War
Ministry of War is a strategy MMO, set in ancient history. Players start either as Persians, Egyptians, Romans, or the Chinese, and expand their lead by building their city and conquering enemies. The ancient civilizations are well-detailed, and each playable nation has its own ‘feel’. That’s not to say the nations are different in terms of troops or buildings, though. The combat system is unusual among strategy MMOs, as combat is real-time if you opt for manual fights. The game is time-intensive, but has the player progress through four ages, thus justifying the time spent in-game. Again on the flip side, the player base doesn’t seem very large, and the translation is rough at times. That being said, however, those who like similar games should at least give Ministry of War a try – the game is fun, even with its slow pace and linguistic peculiarities.

My Lands
My Lands is a fantasy-themed strategy MMO. Players can choose from four races and engage in expanding their empire, conquering other territories, forming alliances, etc. Players earn real money through My Lands, by hunting Black Gems. In order to do that, however, players have to purchase a paid subscription. The game has some innovative features like mentorship, which encourages experienced players to aid newbies; moreover, My Lands promotes social play through social quests and alliances. The developers probably wanted to spark competition (and earn more money) by introducing cash prizes, and rightfully so, as it seems that the cash incentive has made the game fiercely competitive � within the paying community, at least. (Update: as of April 2017, My Lands no longer allows players to withdraw cash prizes from the game.)

Mythic Reign
Mythic Reign is a text-based RPG, played in the browser. It’s set in the dark world of Ozryn and has players fight for their share of the land. The game features many areas to text-plore (sorry!), sports ample opportunities for character development, and even hosts role playing forums and chat rooms. Characters can be customized, allowing players to choose from 12 intricate classes and 4 elements, which play a great role in the PvP. The basics of the game are introduced with a long quest list, helping players shape their character by way of learning experience and skills, gathering resources and joining leagues, chats and forums. There’s certainly a lot to do in Mythic Reign after the initial quest chain. The story gets introduced gradually and is told in bits and pieces, the pace of which players can control. The game world is ample and interesting. Mythic Reign is a rather intricate RPG and players who appreciate text-based games will surely like it. It has ample opportunities for socializing and, even if there’s no mass appeal in it, the game has a degree of polish uncharacteristic for such titles.

Mythic Saga
Mythic Saga is an isometric MMORPG played in the browser. The setting is a weird mash-up of Chinese culture, Greek myths and the western canon; for example, get a load of this -- one evil character is the Marquis de Sade! Besides the four classes (Warrior, Assassin, Mage, and Priest), three factions, which only matter for the side you�ll take during PvP, are available. Character customization doesn�t quite hit the mark. Auto questing and combat make the gaming experience casual, at least during the beginning levels. The experience rate is very high. Mythic Saga features lots of different, imaginative mounts and plenty of crafting. Players who enjoy trading will also have things to do in Mythic Saga as the auction house is available. Selling and buying gear is convenient due to a simple �gear level� system. The story is at times cute and at times frustrating because of the often awkward translation.
