There's so much to consider, and so many good PS1 titles. Right now, I have downloaded:
Final Fantasy V
Final Fantasy VI
Final Fantasy VII
Final Fantasy VIII
Final Fantasy IX
Vagrant Story
Chrono Cross
Chrono Trigger
Castlevania: Symphony of the Night
Command and Conquer
Crash Bandicoot
Crash Bandicoot 2: Cortex Strikes Back
Crash Bandicoot 3: Warped
Not to mention the Resident Evil Games, Metal Gear Solid, Twisted Metal, dozens of others. What I'm trying to say is that there's little chance you can go wrong. If you're looking for adventure, Castlevania is likely your best bet.
Or screw it and get Journey. That's a game you can't go wrong with.
