I was wondering if we should make famicom a synonym of nes. I ask this because essentially the hardware is identical, the major difference being that the plastic cartridges are keyed differently so one won't fit in the other.
As an aside, I should point out that famicom-disk-system is a hardware add-on, and thus definitely merits a separate tag if that should come up.
The two games in the answer to the single famicom question appear to only have been released for the Famicom; the wiki articles don't mention the NES, anyways. To me that implies that there are Famicom-specific questions and that the tags are useful if separate.
They are different systems; leave the separate. The Famicom is the Japanese predecessor to the US NES. They will not play each other's games.
I would propose keeping them separate, since I know of at least one Wikipedia article that indicates the game was changed while being localized to North America. Therefore, a question about the Famicom version could have a different answer than a question about the NES version.
