One of the more popular MMOs out there, Ragnarok Online, has joined the league of MMOs that has gone free-to-play.
Instead of the monthly subscription fee, there's instead the option to pay for a VIP Package. VIPs do get a huge range of bonuses, though, such as:
· 1.5x Experience rate
· 1.5x Monster drop rate
· Increased Kafra Storage
· Less experience loss upon death
· Access to special areas and Buff NPCs
· Access to create characters on all 9 character slots
So, essentially, the free-to-play mode is a demo. If you try the game, and like it, you're probably advised to upgrade to VIP status.
Still, it's nice to have that try-before-you-buy option.
