Yep, that is Snake Eater. Some really funny stuff. Like if you are in the "cure" menu and you spin him around a lot, when you come out of the menu, he will toss his cookies...if you don't have any medicine after eating something that went bad, you can do this. This is the attention to detail, the really weird little extra things, that really make this game so unique and so deep in terms of play. You can approach most situations in many different ways, so the experience varies every time you play it. The bonus "Snake vs Monkey" games were hilarious and fun too. I bought the Subsistence edition thinking I would be able to use my saved games only to find that I would have to replay the whole thing....doh.
Mine also plays in 4:3 mode on the PS3, while all my other games play wide? Did I miss a setting somewhere? Wasn't there a 16:9 mode on that one?
If you haven't checked it out, Okami is also an excellent game for the PS2. It took me 62 hrs to complete and I still didn't find everything. Great story, great game play, but the funky way people talk was kind of annoying.
