So 'tie ratio' is basically number of games sold per hardware unit? Interesting. For example, North America seems to buy about 50% more games per unit than Japa

So 'tie ratio' is basically number of games sold per hardware unit? Interesting. For example, North America seems to buy about 50% more games per unit than Japan, with the exception of the PS1 and (S)NES. I wonder if/how this affects the projects of different studios? E.g., should we expect games from Japan to tend to have broader appeal?
