So. FFXIII and Duodecim.
[spoiler]Duodecim: Lightning's voice acting is fucking atrocious.
XIII: Lightning is overrated. For fuck's sake, she can't even Bright Slap a whiny emo kid.[/spoiler]
Final Fantasy's got all kinds of problems. "10 was too linear, 12 was too freeform, 13 was too linear" being common complaints. Then you account for the storylines following a formula, and the lead characters often having no personality (especially true in 12).
In other words, avoid SE's mainstay titles.
Actually, I find that that 10 was one of the last few 'good' FFs. 12's problem wasn't that it was too freeform, it's that it was too BLAND. It was like a single-player MMO. 13 at least has been delivering a relatively good soundtrack. But aside from that, there's only a couple of REALLY likable characters, and they have next to zero screentime. The rest can be summed up as too bitchy, too moronic, and too "cooler-than-thou".
And Dissidia would be better if they finally got it through their heads that THEIR ENGLISH VAS SUCK DONKEY BALLS.
