I'm more a tabletop RPG person than an MMO person, so btw tests I relax with my mobile games.
The one I've played longest is Gems of War, which features match3 turn-based battles with tons of different types of creatures. I highly recommend it as a time-waster and general relaxant I've got a chill guild and it's got plenty of opportunity for P2W but if a person is just Cheap2Play like me, they can still do quite well.
I'm also following with great interest the development of another MMORPG, based on a tabletop game called Wagadu Chronicles. The universe for this D&D type game is based in African mythos, and I'm totally psyched to learn more about that! Nice change from the usual Euro-fantasy elves and dwarves.
[n.b., I've got nothing against the Eurofantasy thing! I love dragons and Terry Pratchett and D&D all to bits, but the world is a BIG place, and there's a lot of way cool mythos to explore in Africa, Asia, South America, the Middle East... Why limit ourselves, y'know? ]
