The Elder Scrolls Online you do not need a sub for but I like subbing to it when I feel like playing because I like supporting what that game is trying to do. It also has an intriguing monetization system where if you sub you never have to spend extra cash on the game shop. Anything you buy there is purchased with crowns (including things like character services) and you can get a monthly allotment of crowns with the sub. *IF* FFXIV had to go free to play (which it won't) it would be nice if it did something similar.
