I recently picked up a used copy of the original Shadow of the Colossus for my PS3, having never played it before.
Fun game. Cool Music. But I'll have to agree with Nabster regarding the controls. They kind of sucked. It's like the game designers purposely programmed some kind of clumsiness algorithm into the character. You get used to them eventually, but they're far from user-friendly.
I'd be curious to see how it fares with an HD upgrade as it was definitely a beautifully rendered game. Although, one might be inclined to complain that all that beautiful rendering was for naught since the game does not encourage or reward exploration.
Also, fuck that stupid horse.
