Reddit, which video games do you consider your all-time must-plays?

I was inspired by the best video game music thread. These games have made me feel empty inside once they were completed.

I have to go with:

• Bioshock Infinite
• Kingdom Hearts 1 and 2
• Final Fantasy VII and X
• Okami
• Red Dead Redemption
• Super Mario 64
• Legend of Zelda: Ocarina of Time/Twilight Princess/Skyward Sword
• Every canonical Metal Gear Solid Game
