From what i understand from the box and Wiki, its like Guild Wars, you pay for the CD's but the online content is free.
Its ment to be alot less "gay" PvP wise.
Like in WoW caster players are foced to stand in one spot till the spell is cast, in Fury you can run around pot shootting people with fire balls.
It sounds fun. Its all PvP based, so no crappy questing.
