Every single MMO I've tried eventually turned out to be:
1. Utter Grinding
2. Moneymilking
What exactly this thread should answer? Which MMO milks money the best? Or something else?
I see Maplestory up there… That one has also a third "ability":
3. Cheat to win
And you're nominating that game? OMG…
In any case, if you want to know which one I had most fun with, it was DDO. What took me away from it was - lack of humor.
Enough humor, but pretty childish and more grinding than DDO had was Wizard101 so I had also much fun with that one. But lack of puzzles drove me away from that one.
