Functionally both forums work for the same thing, so you really should've just posted in that topic. But that's beside the point. I played RaiderZ, and it's definitely a good game worth giving a shot. I don't have the time to dedicate to that right now, what with work and TERA going free to play (I've got founder's status so I'm gonna go back).
Absolutely recommend RaiderZ for anyone looking for a new game to try though.
