What I experienced in this game was other users on the chat talking about gay people. Not really appropriate, right?
I think I just got unlucky when that happened though. So if you ply just be careful about the chat.
I Played "Dungeon Runners" for about a week. There really are not that many skills to choose from. Gameplay gets old, and really only members can have all the cool stuff you pick up, It's as if they are mocking Free-To-Play players. Constant ads throughout load times are also a turn off.
