Tera was my first MMO in my mind because i did not play Star Wars the Old Republic long.  An MMO is a massive multiplayer online game.  Tera was made to have a very bright a in your face world.  There was one zone that the trees where white and pink, bright pink.  I never finished leveling all the way up in Tera because most of the people I play with got bored but i was close.  I look forward to this going Free to play because I will play it more.  I really enjoyed it and thought it was a pretty envirnment.  At this point I would advise you to wait till it is free to play before trying unless you have a group of friends to make it worth paying monthly for.
