I've been playing SEIV:G.
I played a bit of FF: Tactics Advance, but... I can't say it sucked me in like FFT, even though it's better in some ways...
If anyone is looking for a great game, I suggest Xenogears. I always feel useless saying that, like when I suggested Dominions on AOW or MOO3 forums, proclaiming it the deepest strategy game ever, to overwhelming silence...
But, hey, if you made it all the way to the Dominions forums, it means you're SERIOUS about finding good games! And I think Xenogears is the best game ever. Yes, better than Dominions, System Shock, or Star Control II. Though not better than all three combined
