Ok lets try this approach take 2 games that you liked and compare them (SE Games I mean). I loved 7 loved how the materia worked and just everything about it. When 8 came out they changed everything. I hated 8 lol.FF1 was very different the Ff2 and so on. SE tends to change things when they make a new game. Love it or leave it thats what they do.
Xi has been out for 8 years in the states, and most of the list i keep seeing was added with expantions (I am not good at spelling btw lol). Starting out in a new game you have to lvl so really lets think about that. Will you get to do end game or other content if your not high enough in rank? So might as well get that out of the way so you can enjoy all of that content that isn't there atm but will be there soon enough.
Take it as you will but that is my take. I didn't come into XIV looking for a new XI.
