Still a hard disagree. It sounds more like the folks who have this mindset are simply bothered because it isn't their favorite studio putting out these games, not that the games don't exist.
This generation we got stuff like No Mans Sky, Fall Guys, Hotline Miami, Overcooked, Cuphead, Untitled Goose, Superhot, Surgeon Simulator, Don't Starve, Rocket League, Towerfall, Stardew Valley, The Witness, etc etc etc. I can go on and on listing tons of incredible indie studio games of varying lengths with completely unique styles and genres...the idea that there's anything different just because of something arbitrary like studio name or team size...nah.
I think people maybe forget how small teams were on PS1-PS2 games. So many of the games people love were made by 50 people or less. Those games weren't made by behemoth 200 person teams.
The variety is there, it's just a combination of nostalgia and turning your eye to something because it's not from a studio you recognize. That's it.
Like I said above, those games are basically "indie" games. The team sizes for those titles, budgets, etc, were all basically what indie studios have today. The only difference is they don't have to team up with a publisher for distribution, they can link up with a platform holder and do it digitally for a fraction of the cost.
