honestly, if I didn't have already have a bunch of games that I want to play or have my eyes on, I'd probably try some of these completely random games making it onto NSO to see if any of them are maybe actually decent or not terrible, or basically see if they actually deserve to get **** on. You could call it a curiosity thing.
As I say, I think its great to try to add obscure games very few people have played on the NSO...as long as they aren't garbage, which I guess is why I have my aforementioned curiosity over these games.
That said, even if some of them were actually okay, Nintendo still really has to do a better job getting more notable retro titles onto NSO.
