I loved FFX, it was one of the few FFs I kept going back to after completing it (namely for the massive amount of sidequests, cactuars and monster arena). I also really loved the Sphere Grid. There are so many moments and features in FFX that make it one of the best Final Fantasy games to me; I'd have to say it's a favourite along with IX and IV.
Anyone else playing The Legend of Zelda: Spirit Tracks? Wait, don't go! It's ok! They fixed most of the problems from Phantom Hourglass! Seriously though, Spirit Tracks is really enjoyable so far.
Planning to finish up Persona 4 soon and start a new game+. I'm in the last dungeon (the normal ending one anyway, aiming for the true ending afterward), so that won't be long off. Speaking of Persona, I'm working on a game in RPG Maker that mixes the Pokémon world with elements of the Persona games. It's turning out pretty well so far.
