Final Fantasy XIV is gorgeous. The developers clearly put a lot of time and energy into creating all types of climates, ranging from harsh, desolate deserts to untamed, icy wastelands. The cities and villages in this game are vibrant and alive, while the cinematics can be dreary and depressing.
Apart from the landscapes, the spells and abilities of this game will take you by surprise. Every ability is animated very well, and has gorgeous pixel designs to pull you even further into the game.
Most MMORPGs don't offer much in the way of a story line, but that is not the case with FFXIV. The story will span the entire world, and is completing it is actually a requirement to get into most of the game's content. However, it doesn't feel like you're being forced into following a story you don't care about, the characters get into your head and you begin to feel like an actual hero.
It's very well written, and can be listened to in multiple languages if you prefer that.
The combat in FFXIV is incredibly polished. It requires quick, real-time decisions and reactions, as well as a plan for how your team is going to take on whatever you're fighting.
Like many games, it begins as simply hitting your attack buttons and waiting for your abilities to be ready again. FFXIV, however, has taken it a step further and has implemented complex combos and other interactions. These other interactions often have wildly different end results, so you must decide how best to use them.
