I shouldn't really be one to judge Final Fantasy since I haven't played it, but from what I've seen it looks like Guild Wars 2 x Skyrim. The spells, the weapons, the Dragons, the movement. On their own though, Guild Wars 2 and Skyrim are quite alike gameplay-wise, the only real difference is that the combat is fought differently and the map, of course.
Speaking of which, I always wondered what it would be like seeing a multiplayer arena in Skyrim. We only ever battle in singleplayer and it would be nice to see some multiplayer action going on, that would make all Elder Scrolls fans happy.
