FFXI doesn't count for me (but if it did, that one) but it would have to be FFXII, you don't take out turn based combat AND/OR random encounters, its what made FF...well FF.
Also to anyone arguing with the random encounters bit i say this: "in YOUR games, you enter a small room and you have about, one or two enemys, you kill them, end of, right? But what if thats not what you want? With random encounters a small room still has infinte enemies, and at that, anywhere can be a battleground for infinte training. Besides don't you love the screen disappearing, then finding out what your about to fight?"
And to the people against turn based combat, i also say this "Bet you play a load of FPSs, right? Well tell me something, when your playing FF (if ever) how many times within an hour do you die? Well let me tell you something, with turn based combat, i can get a plan of attack, the curing, the items, the defence, and the attacks perfectly rounded before i even actually lay a hit, and ergo i tend to stay alive/beat strong badasses/keep heath up/use less items then needed etc. Now tell me where turn based combat is bad in that respect, without mentioning how slow it goes".
I've made my point i think.
