This was legit the best MMO experience I've ever had back when it came out. I played it on PS3, then PC, then PS4.
It's archaic at this point but its style, atmosphere and charm make up for a lot. Plus the movement skills are great (flying and acrobat at least) and the combat is still great. Feels awesome to beat the shit out of some mob.
Amazing that this is still going. And amazing we've never had a sequel.
