How come Nintendo keeps having to completely reinvent itself every couple of years? They go from being on the verge of bankruptcy to a hit then back again. It seems like one tiny misstep and they're done. Microsoft is still spending accrued value from the 90's after tons of mistakes, why doesn't Nintendo have an easier life?
And for both companies gaming is important but so is providing media and services into the living room. Nintendo seriously has missed the opportunity every generation to expand beyond gaming and so they are more susceptible to the strength of the games themselves.
