You said they at the same point in their lifespan GCN had much better support than Switch.
Now you are saying that ports of flagship titles don't count, smaller games don't count, indie games don't count, rereleases don't count, etc, which is a huge supossition.
As a GCN only owner, I would've been ecstatic about announcements of ports of PS2 games like FFX, MGS2, DQ8, etc.
The truth is that Switch's Japanese support obliberates GCN's support. Sure, there's nothing like RE4, but what is as big as RE4 nowadays?
You have been proven wrong, end of story, just let it go.
