This has been lingering in my mind for a couple of days, ever since Gizmodo posted a story about the .GIF extension and if you say it like the peanut butter (Jif) or if you prefer another way.
This got me thinking about something else: ICO. That wonderful, loveable, spiritual predecessor to both Shadow of the Colossus and The Last Guardian, made by Team ICO. You can see my initial post over at my Speak-Up post at Kotaku.
My question to you is this: how do you pronounce it? Answer by taking the poll you see off to the left of this post (or at the top, left-hand side if you didn't get here by permalink).
Personally? I prefer "eee-ko". Not only because that's just how I say it, but it's proper Kana.
