As a PC gamer who is basically completely new to the FF franchise (my brother recently bullied me into being his paladin in XIV, and I'm loving it, but I haven't played a single-player main line FF ever), what's a good one to pick up during the sale to get me started? After reading up a little bit, I'm kind of overwhelmed with navigating different versions of the same game, the order of the games and if it's important to play some of them first, being wary of some questionable (?) PC ports etc.

Any guidance from the lovely veterans here would be much appreciated!
