Seems to me like some people don't actually post "unpopular" opinions per se.

- Tidus is a great character.
- Yuna is a good character.
- XIII was a good game, not nearly deserving the hate it gets. XIII-2 brought the level back to awesome.
- X-2 has the best optional challenge in the series.
- VIII's Junction System was pretty cool.
- I think it's great that SE keeps experimenting with FF even if many don't like the recent outcomes.
- X is the best in the series.

And finally:
- All the games in the FF series I've played (V+) are good games.
