Legally speaking, Flying Lab is required to give players 30 days notice before making changes to the subscription and payment system for Pirates of the Burning Sea, which they surpassed with flying colors thanks to the presence of some game busting bugs, not to mention the Thanksgiving weekend. After a long wait, players can finally play Pirates of the Burning Sea for free…partially.
As far as content goes, free players are restricted from premium missions, which can be purchased at the shop. Otherwise, the system is pretty traditional. Character slots, dockyard slots, ship storage slots, economy slots, ship insurance, and a few other things must be purchased from the item store. Premium accounts get a bump in the restrictions, and premium is automatically applied to those who subscribed in the past (with good account standing) and those who subscribe for even just a month. Captain’s Club members (the $15 a month crowd), gain full access to the game, with added bonuses of a 20% discount to everything in the cash shop, automatic access to the premium missions, and a 10% bonus to loot, experience, and faction standing.

If you’ve been holding off playing Pirates of the Burning Sea, now is the best time to get in. You can’t go much lower than free.
MMO Fallout 
Yup, I’ve played it a few hours today and it’s kinda fun. You get to ride ships and battle it out at sea. The graphics isn’t bad either.
