If you ask me, both retro games and modern games both have their ups and downs.
Sticking to just retro games isn't exactly the best thing to do, but if that's what you want, then hey, I can't stop you.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
