Ive just downloaded ragnarok re:start. havent started playing but I know Ragnarok Online. I looked at the User License Agreement and it says there's a billing in US dollars and that gravity can change it anytime. Does this mean it is not free to play? please answer. Any info would greatly help me in understanding this because I'm a bit paranoid. Here is the part where it says so.
