I started with Final Fantasy VII. After that, I played Chrono Trigger, and I eventually played FFVI. I played several FFs after that, but I completed them in this order: FFVIII, FFIV, FFIX, FFV, FFIII, FFI, FFII, FFX, FFX-2, FF Tactics... and that's it. I played many of the remakes after that, and I also played the Kingdom Hearts games, but after finishing FF Tactics, it took me almost 3 years to get to play an FF I hadn't completed before, i.e. FFXII.
