Summons
Vivi and Existence (+Cloud and Identity)
FF Politics
FF Siblings
Square Enix and the Mobile Gaming Push

These are some of the random things I have written down. I also want to write a sequel to my airships article where I look at non-aeronautical means of transport. I also think there should be several more entries in The Lore You Know, including the likes of Ultima (Weapon), Ragnarok, etc. I should do a romance piece as Wolf Kanno suggested. Then there is always room for things like Top Ten Minor Villains, a random thing about how there are pianos and lutes and trout referenced all through FF, etc. You know. Just stuff.
