I've been very busy on my supposed "week off" - I haven't touched a video game since my last blog spot, believe it or not. A Player Diary for FFIV is looking highly unlikely now, but I can affirm that the story, with its focus on light and darkness, seems to lean closer to the Christian view of things (where things simply are or are not good than the ying/yang Taoist dichotomy that ulitmately makes everything a collective abyss. It's a long play-through, and it's frustratingly difficult at times, but this makes the experience all the more fulfilling.
In Story of a Soul, St. Therese tells us that God allows suffering in order to bring us closer to Him; in the psalms, we learn that God chastises those who are close to him. Final Fantasy IV DS reflects this in both its narrative and in the actual gameplay itself - as I said, it's a long haul, but it's worth it in the end.
