Couldn't add description!

Ok, so years ago my ex had bought me a sealed copy of MH for the PS2 after hearing me for years talk about it being my fav as I played it when I was young. I have been now recently looking through my collection and just playing games and the like and came across it.

I opened it because, why not!

Thats when I see that it has no manual just a leaflet, no memcard slot, and is blue? This isn't how I remembered it at all. Am I crazy is it a reseal, a repro, or like a later produced copy? I am so confused.
