Coolness is often a matter of perspective, not the content being advertised. Look at the N64's Get N or Get Out campaign. The games shown were Star Fox, Wave Race, Mario Kart 64, and Super Mario 64. Yet the attitude and tone made the Nintendo brand look cool. That's what good marketing does: presents things in the right light to make them appealing. Honestly, when was being a plumber who jumped on turtles and ate shrooms ever "cool" outside of the gaming world where Nintendo's marketing MADE it cool? :P
Actually, scratch the first bit. Coolness IS a matter of perspective. Just look at all the myriad of trends and such that start up, purely because a specific thing takes on the "appearence" of coolness without really changing, where the marketing casts it in the right light.
And Nintendo has many games that I think could have a wider "cool" appeal. Xenoblade and Metroid are the standouts.
