Look at the threads about great XB1, PS4 and Wii U games.
Constantly the response is "that's on other systems so doesn't count" and even more so with digital.
A game like Shovel Knight, is on PC via Steam, and Wii U via E-Shop. Great game, absolutely what I want to play. If someone dared say in a thread saying Wii U doesn't get enough games because Nintendo don't make enough or whatever, it'd instantly be dismissed A because you can buy it on Steam as well, and B because it's digital only.
The Last of Us Remastered is another example, as is Halo collection etc. Yes, the games are on other formats (actually previous gen) but why does that make them any less a part of a console's lineup. Most people tend to have 1 or 2 systems at most anyway.
I appreciate that an exclusive game can help to sway a buying decision and being physical on store shelves gives it greater exposure. But why are they not counted towards a systems lineup purely for being available elsewhere, or not shipping in a box? They're still part of that system's software lineup.
