I was actually tempted to, even though I don't have an SG-1000. The cassette version is MUCH cheaper than the cart one, albiet less cool =P
One tiny niggle about that packaging (not intended to dissuade anyone from purchasing it) - if it's supposed to be period-accurate as compared to other SG-1000 games, it's sure got a lot of Arial where Helvetica would have been more appropriate :P
