I don't recall the N64 Expansion Pack doing that well... but then I never had an N64, so I'm probably missing some details. Mind clarifying them for me?
As far as the chips go, weren't those on the games themselves? If it's hardware that's on the game cartridge itself, I'm not counting it. If I did, I may as well include save batteries and ROM chips. Thanks for bring it up, though. It seems i was not as thorough as I'd thought.
I'm on the fence with Satellaview. It doesn't sound like the games are actually a step up in terms of technology, but you could still argue that stuff like the live broadcast enhances the game. Hmm... For the moment, I'm going to lean towards "not an add on," but I'd be more than willing to hear a counterargument.
