I was wondering about two things, not sure if someone has brought it up.
First of all, would it be possible and feasible to downport multiplatform console games to the NX handheld? If the handheld supported UE4 (or at least the mobile version) could one port it to the console NX and transfer the assets to the portable downgrading them to run well enough?
For example, take DQ 11. If the port to NX does happen, I'd imagine SE would love for it to be on the portable as well.
Being turn based you wouldn't need it to run particularly well.
Would be interesting to see them try it. Would likely be more successful than their Hyrule Warriors attempt.
My second topic is the possibility of 3DS emulation on the NX. I don't think BC will return for either device, Nintendo likely leveraging the Wii U's library via remasters, but I'm not sure about the 3DS's I'm not sure. There are a lot of 3DS games and I'm not sure most of them are worthy of a full remaster or a retail re-release.
So I wonder if 3DS BC is possible. I think it could work, not sure if emulating 3DS would be more intensive than GCN, but it seems doable on the console at least.
Though I'd like to see it perform at a higher resolution and I think a lot of people would be willing to double dip, they didn't do anything like that for DS or N64 so I'm not too sure they will.
I believe this would be the best way to leverage the 3DS's large library.
