I've recently fallen in love with DFO, in spite of Nexon's dire wishes to totally screw up the launch. It really does feel like an old school arcade fighter meshed with a slightly less old school dungeon crawler, which comes together in a great combo. The combat is fast paced and more reaction and skill based than most of the MMO's out there. They even have a token system which functions exactly like popping quarters into an arcade machine. When you die, pop a token, and come back to life to finish the rest of the dungeon. Highly recommended to anyone who wants a break from standard MMO fair.
