Clearly the best type of article for me would be to do an opinion piece, a blog piece so to speak. Now clearly it has to be FF related/Square-Enix related.

Current ideas knocking around in my head:

Coolest FMVs in the PSX era
Airships, why they're so prominent in the FF series and which would be the most realistically attainable aircraft in the real world.
The FF9 ability system versus the materia system of FF7.
