console with 58 games only came in 9 minus PAL version

Well, in the US, the 7800 was out for almost a year before the NES hit our shores. Also, it had better resolution (7800's 320x240 vs NES's 256x240). The NES also cost $60 more. That being said, the NES has far better third party support, and better sound.
The 7800 still has the better version of Xenophobe, though -- the NES one is pretty bad.
