It's depends on what day of the week it is, ask me tomorrow and I'll say something else but I'll go with Skies of Arcadia today. The premise of sky pirates, floating ship battles and so many secrets to find in a huge open world was magical for me and replaying it only made me love it more. That said, I'm ashamed to admit I've played well over 3000 different games and I'm a bit obsessive over lists. I made a top 100 once and every single game was an incredible slice of my youth and happiness. Even leaving a game off that number was heart-breaking so naming just one is just impossible to keep consistent. Weirdly, I can't say the same about films - my top 10 is pretty much set in stone. I guess it's the way games are "flavoured" by the events that happen around them. I can place games with the albums and films that came out at the same time. They pick up the anecdotal stories every one has about how old you were, where you played them, how much they cost you. They're a little bit of magic for me.
