Very cool, and higher sales than I'd have thought... 3.7 million (and that not a complete number) isn't too bad, for a system sold with bargain-basement production values and game development costs. Interesting.
Oh, and yeah, Ninja Golf had just come out in 1990 I think, so that's just the early sales... and no 1991 sales are here, much less those O'Shea's and stuff, so yeah, actual game sales are definitely higher. But it does say that early sales of 7800 games in 1990 were pretty poor, for some games at least...
Still that is kind of odd, though... were people mostly playing 2600 games on them, or something?
