I think I figured out Kytim's obsession with Rare games on Nintendo consoles. Kytim is the son of Nintendo and Rareware and he is still upset by their divorce. Like any kid it is understandable that he can't imagine his mother with another man (Microsoft) and dreams of his parents reuniting (via the Virtual Console). Nintendo's inability to keep steady 2nd and 3rd party 'partners' in recent years (Silicone Knights, Factor 5, etc.) means that Kytim has been missing that all-important 'mother figure' in his gaming life.
Maybe things would have been better if Nintendo and Rareware had gone to marriage counseling.
