Love or hate? Those are two very polarizing options. I'd think most people would vote for somewhere in the middle ground before they voted that they hated the game (thus there being only 2 hate votes in the OP's poll as of now) so it's a little slanted in love's favor. That said... I loved this game.
I agree with most the points Shadow-3D made on the first page, though I've not played Arkham Asylum, so I can't really comment on that. But yeah; loved the exploration and discovery in this game. I know that isn't everyone's cup of tea-some people want to be directed where to go at all times throughout the game. They could never get through a game from the Fallout or Elder Scrolls series.) Also, a few of the characters are my favorite in the series: Locke Cole is my favorite thief, Terra Branford is probably my favorite protragonist, Mog is my favorite moogle, and Kefka is by far my favorite villain.
One page back, someone mentioned that Terra doesn't get the same hate Cecil, Cloud, or Squall get for it. I dunno if that person is still around to see this, but here's my thoughts on this:
1. I've never seen anyone hate on Cecil. Maybe it's the different forum communities we hang out at, but... yeah. Don't see it, there.
2. Cloud was introspective and depressed... and then he got more introspective and depressed after the end of the original game, in Advent Children or any other subsequent appearance he made in a game. We get ridiculous lines like "I won't be able to sleep tonight" after he wins fights in Dissidia. He helped save to world, there was a hot girl there who really liked him (and helped him rediscover himself)... and yet he couldn't get over this other girl's death, and needed to be forgiven for it when it wasn't his fault. So his whole depression and introspection starts to delve into cliche emo territory.
3. I'm pretty sure Squall gets hated on because he was a cold, unfriendly dick for much of the game, not because he was depressed or introspective.
That's how I would explain that. And unlike those other characters, up until the very start of the game, Terra had no family or friends, and no past. She was like a child in a foreign world, trying to figure things out for herself. I think she has the most right to be introspective and depressed, heh (although I never really saw her as being depressed, really...) Also, a bit sexist, but... she's a girl. She gets a little more leeway to be emotional. Guys are supposed to be tough and strong, and never cry, didn't you know? Anyhoo...
