It's hard to vote anything other than FF. While other series amy have 1 or 2 games that outshine some FF games, FF has been the most consistent over the years and has more games worth playing than any other RPG series. KH has only 2 main series games for instance...while they were really great, they just cant compare to the sheer number of great FF titles.

"WAR is a racket. It always has been.
It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives"---Maj. Gen. Smedley Butler
