trickster

they hold events from time to time, theres allot of players, u can get free cash points by doing surveys, has kick *** gameplay and music and because the leveling goes so fast(begins to slowdown arround level100 lol) and theres so many areas/monsters +lovely mainquestline it never got me bored

its a real timewaster though and u gotto try liking drilling(digging ground) for minuts if not hours at some point later in the game but drilling is the way to get rich by putting quest items in your usershop.
my favorite f2p mmo overall
1 downside for some people: trickster will not run on windows 7 32bit (but maybe there is a fix already)
