If you like the layered politics sort of thing in FFXII, you would very likely enjoy Final Fantasy Tactics: the War of the Lions, whose plot and characters were designed by the same guy (Matsuno, who also did Vagrant Story.) It's a grid-based strategic game (no button mashing whatsoever) and even if you suck at strategy like I do, it is totally possible to level grind until all the plot battles roll over and beg for mercy.
