SK prove skills and talent on ED, one of my favourite games ever.
But MGS just dissapointed, I didnt even like it as much as MGS2 (maybe because MGS2 was so wow when it came out)
Anyway, SK might release games for GCN, but I cant see them making any more exclusives, why should they? Its always a risk to make a GCN exclusive from a business standpoint, and I cant see Nintendo giving them lots of cash for exclusivity, otherwise they wouldnt have sold SK.
