plus, looking through the nes library there seemed to be a soft ban of arcade ports. it wouldnt surprise me if publishers were strongly encouraged to release console specific games rather than release arcade ports the same way sony discouraged 2D games on the PS and PS2.

I have never heard this before. Is this documented fact, speculation, or somewhere in between?

It's just that by 1987-88, NES gamers expected far more depth (& longevity) from their games than straight arcade ports could deliver.
