I always recommend the same ones, with the addition of lesser-known or popular titles:
- Disney's Hercules, Resident Evil 2, Final Fantasy VII and IX, Pepsiman and Donald Duck - Quack Attack for PS1 (there is also the PS2, Dreamcast and PC version, but I honestly preferred the PS1 version);
- Medal of Honor Frontline, Crash Nitro Kart, Final Fantasy X, Shrek 2 and Spider-Man 3 (yes, I like tie-ins, I'm weird xD) for PS2;
- Civilization III, Black & White, Age of Mythology and Caesar III for PC.
It depends on how much time you can dedicate to video games, but trust me, they are real gems.
Even Pepsiman
