Why don't multiplatform and digital games count?

[Kantor]

Digital games are often smaller in scope: shorter, lower budget and so usually less notable even if they can be excellent games in their own right. Of course, this isn't always true.

Multiplatform games are omitted when doing console comparisons, but not otherwise. I suppose some people do have that mentality of "people who own other consoles can play this, so I don't like it as much", but they're a small minority.
