the benefit of the steam version is that streaming it to the TV is less finicky and you can pay for gametime using steam instead of mogstation which also means using paypal without having to purchase crysta or whatever its called.

its still infinitely inferior to the standalone ver. but as someone who has multiple friends who have never played an MMO in their life who then wanted to try FFXIV, it's a life saver. the mogstation site even after the update is both confusing and also kinda shady looking when it suddenly reverts to the older look on random pages.
