Runes of magic

digimon masters online

The Elder Scrolls Online soon...

Smite isn't an MMO. O.o

GW, Tera, Aion, Rift, SWToR, Conan, Eve... I've given them all a try, but keep going back to WoW. Looking forward to GW2.

World of Tanks

None.

Since real mmo's died a long time ago.. now we have shit like GW, WoW, Conan, Rift, Swtor, TSW... none of them are above avg.. Eve is the only above AVG..

If we are lucky, TESO will break the cycle, but tbh.. I actually don't think so

WoW

Dragon Nest

Used to play Anarchy Online with all expansions and not free one.

I play WoW on-and-off. I'll probably pay for another few of months soon for until I get fed up with MoP. I'm not big into MMOs, I just (used to) really love Blizzard games, especially the whole Warcraft universe. It's the world in the game that keeps me engaged, at least for small periods at a time.

runes of magic. ( free wow )

Dungeon Fighter Online. Oh wait, that's on Steam now.
Cosmic Break (Careful. Very strongly Pay-2-Win and will EAT YOUR MONIES).
FIREFALL!

The only MMO I play is Dungeons & Dragons Online, but that's on Steam too, since the new expansion.

Not playing any MMOs at the mo. But I used to play:
Anarchy Online (with sub, put in thousands of hours)
9dragons (good combat, nice community, but definitely pay2win and also a huge grind)
Dekaron (hacker infested, too much of a grind, has nice pvp though and a very fair item mall)
Requiem (the setting/atmosphere is great, but yet again a boring grind into oblivion)
Perfect World (simply boring)
Runes of Magic (dual class system is just a double grind)
Atlantica Online (definitely had potential when I played it, but when my guildmaster emptied the guild bank, and ran off with everything while simultaneously disbanding the guild, the fun was gone)
Martial Heroes (is dead now, I liked the retro graphics but the community hardly spoke English)

Also tried out many p2p mmo's, but none were worth paying. WoW came close though (was years ago).

I used to play WoW and EQOA (EQ full blown MMO for the PS2)

Shaiya

Nice and shiny. I don't think my car has ever been that shiny.

Continent of the Ninth Seal (C9)

Such a shame this got trashed.

MechWarrior Online

Used to play lineage 2.
