As a person that has been playing RF for well over two years, I say RF is good. But it's far from being the best fighting game ever.

*There's horrible lag issues that typical favor the player that's lagging
*No Guild or Clan function for over two years
*Cash items like guardian sets, extra panics, backpacks, turtle shells, omni sensors, critical eyes and more throw gameplay balance out the window.
*TERRIBAD community filled with immature players

If you can get past all that, there is fun to be had with RF.
