I think that's a really key point - back in the days of the PS2 to 360 era, it was all about Xx_Graphics_xX and there were so many 30fps games that dipped to 15 at times, making "30FPS" feel worse than it was.
That said, 30FPS can still be rough. IMO Dragons Dogma 2 running at 30 on the PS5 is pretty rough. Even excluding dips, but it has them. But the game Heroes Hour on the Steam Deck running at 30 is perfectly fine. Similarly, setting Red Dead 2 to get a consistent 30 is fine too.
Consistency is huge, for sure!
Drink when R2 appears.
If you think that's not enough for all 9 movies than add C-3PO.
That should have you well paced for all of them without killing you or being too slow.
