I agree. This sums it up perfectly. Little Mac just easily roles into the mind as a good, solid, likely character (or sexy pick).
And boxing requires a lot of different punches (uppercuts, undercuts, haymakers, Little Mac's super punch, etc), moves, and footwork. I'm sure it wouldn't be too hard to make a moveset in their about it. There could always be punch combos as moves.

I will never consider D&D cool, or a child's toy (aka video games), but rather just there. Cool is simply a state of being.
