TBF Final Fantasy is sub only. All is well if you purchase the ESO sub. The only issue is the lackluster expansions but they're also half the price of FF expansions and
WOW TBC Gold released twice as often. When you can double the size of these at the same cost, it's pretty competetive.
FFXIV also has a critically acclaimed expansion that is called Shadowbringers that has been hailed as one of the top Final Fantasy stories of the past 15 years or so. This is the highest praise I've ever heard about an ESO story.
Do it ! I'm just finishing the base , and I enjoyed each and every moment of it. I don't feel pressured to hurry because Ilevel sync makes it difficult to finish old content. The the fact that there's other things to do other than killing it hoboing up, such as racing chocobo which is wonderful. My acquaintances who have played the dungeons with me won't give up on a wipe, and they will happily assist you whenever you need it.
I'm currently playing FF in the present, but I'm not able to make an argument to not consider ESO. Both games are enjoyable to play in their own manner. Final Fantasy strikes me as much more of a game for social interaction and the storyline is comparable to any main line Final Fantasy game. In contrast, I consider that ESO will allow you to become more involved within the world. ESO is a fantastic method to become involved in the world if capable of identifying your Nirn. The biggest issue for a lot of people appears to be combat. FF appears to be more like WoW. ESO is more like GW2 And later the rotating mechanics of ESO can be a bit bizarre, not from a length perspective, but at an execution point.
They're both very cool and fit into different niches. I personally have enjoyed the story of ESO better, however I've played more Elder Scrolls games than I have Final Fantasy games, so I'm familiar with lore and references quite a bit more often.
ESO has a smoother housing system
buy WOW Classic Burning Crusade Gold than FFXIV doesn't have. It is possible to float and tilt objects without needing to exploit bugs, if anything else. All instances are created in an instance (but large) which means you don't need to compete with other players over plots.
