I went through the issue quickly and looked at the review for Rip Off. It was rated "C" which is "average." Bob did a good job translating the game into the 7800, however. I guess Rip Off is Rip Off.
There's a saying "you can't polish a turd"
Rip Off is an average game - not much substance in the game play and as I stated in the review he probably programmed it with his eyes closed. Definitely not one of the more challenging games for Bob to translate but for what it's worth he did a good job with it.
If I had my choice between the Vectrex and the 7800 version I'd pick the Vectrex.
