If there's an RPG designed for many, many playthroughs, it's this one. I think, because it was made so well, that makes its brevity and general ease a bonus. I have a lot of RPGs I really liked and wouldn't mind playing again, but don't want to set aside 60-100 hours to do so OR there's that one area I really didn't like because it was frustrating or something like that.
With CT, you go from place to place at a brisk enough pace that if there's an area that's more of a drag to you, it'll be over soon. And, after playing it a few times, the only thing that always will challenge me is that boss fight with Giga Gaia. It just brings the pain at the beginning -- if you don't obliterate an arm very early, you will be destroyed by its big group attacks.
I'm not afraid to die because I am invincible
Viva la muerte, that's my goddamn principle
