Well ps1 and ps2 released 1 year before Nintendo or Microsoft and done well, x360 had healthy sales from releasing one year before ps3, so it can help or maybe don't Matter. The problem with the ones that released before competitor and bombed was price was high and specs got trounced. Gênesis saw a great rise from Master system.
