LIQUID OCELOT
I'm definitely going to get back to playing sooner rather than later.
I was also somewhat considering delving into another stealth series sometime soon (likely Assassin's Creed), but there are a LOT of other series I'd rather get to first (e.g. the rest of MGS, FF, Metroid, Zelda, CT, MMX, Portal/Half-Life, heck even the likes of Okami and Xenogears are included there).
