Nearly completed Skies of Arcadia now, just in the last dungeon.
Playing Advance Wars: Dual Strike on and off as well (i.e. extended time periods in the bathroom), up to Mission 15 on Normal Campaign, very easy so far at least compared to the first one, but this mission looks tough.
Well I bought a few portable games to keep my busy during my flight. I purchased Final Fantasy III and Quendan (AKA Elite Beat Agents) for my NDS, along with Grand Theft Auto: Liberty City Stories and Metal Gear Solid: Portable Ops for my PSP.
