Hard to say
I would like to say I would go more retro, but if there are games on a modern, all digital platform, then I suppose I won't have much choice.
I have quite a few games now that are digital, but I don't count them in my collection (save for a few, stuff that is special like the Nintendo 3DS Ambassador line, and things that are currently digital only which I replace once/if I get a retail version).
I think I will go mostly retro though, I have a backlog years long, and there are still loads of great games I want to play before my carts, disks, and hardware start to fail.
The Switch is the first modern console I have bought for since the OG Xbox, and I've been a bit overwhelmed with all the new stuff I have to play/buy. Going back to a focus on retro gaming would be a nice reprieve.
