I own an N64, PS1 and Sega Saturn. The Sega Saturn has like 3 decent games and some good light gun games. That's it. I barely touch my Saturn.
The PS1 has a huge library of games ranging from good to amazing.
The N64 has about a dozen gems and its games are very unique.
The Saturn just kinda sucks. And I say that as someone who loves Sega and wants to love the Saturn.
