I’ve always been a Nintendo fan, and their first- and second-party catalog from the 90s is phenomenal:

• Zelda OoT / MM
• Goldeneye / Perfect Dark
• Super Mario Bros 64
• Mario Parties
• Banjo Kazooie / Tooie
• Pokémon Red / Blue / Yellow
• Pokémon Stadium

Outside of Nintendo, the standout titles for me are:

• Crash Bandicoot
• Spyro
• Metal Gear Solid
• FF VII & VIII
