Best or favorite RPG system

[kainemaxwell]

What do you think is the best, or your favorite, RPG systems? By systems I mean how the game allows you to level up your characters, attibutes, weapons, armor and items.

My favorite system ever, Dragon Warrior 1-4 or Final Fantasy ONE. FF1 had my favorite system of all time. Even leveled up to another class halfway through, best system EVER.
