FFV or FFXIII, in different ways. FFV is rated okay but is actually excellent. FFXIII is rated as rubbish but is actually good. I've not finished III, IV, VI or IX yet. I'm assuming we're not talking about XI or XIV, but if we are, I think XIV is probably pretty underrated now, as it's actually pretty good and that's before the latest patch which the players have been raving about.
