I want to experience the PS1. What are the must-play games?

My honest advice is to skip PS1 and go straight to PS2

Most of early 3D games did not age well at all. Getting a expensive piece of hardware and original discs only to play few games seems a huge waste of money. Look for collections and re releases on PS5, many publishers issues ports that are much less expensive than buying the original discs
