In February, Tera will officially go the route of pretty much all MMOs these days—free-to-play.
Tera will now consist of three subscription tiers: Founder, Elite, and Standard. The Standard tier consists of the free-to-play users, and the $14.99/month subscribers will be Elite. Those who already subscribe to Tera will automatically go to the Elite tier. The Founder tier is for anyone who purchases a copy of the game and registers it. Founder status is good for life, so even if current subscribers cancel their subscription once this new model goes in place, they will automatically be in the Founder tier.
The major differences between the tiers are the number of character slots, bank slots, daily bonus quests, and brokerage postings. There are no limitations with race, class, or content.
