Hmm… Good question… They’ll have to be the kind of videogame that was the first to do something, or set the standard for something, or has had a huge, long lasting cultural impact that can still be felt today.

So in that hypothetical museum I’d nominate:

• Pong.
• Tetris.
• Donkey Kong arcade game.
• Super Mario.
• Super Mario 64.
• Crash Bandicoot
• Metroid (the first one).
• Castlevania (the original one).
• Hollow Knight.
• Mario Kart.
• The Legend of Zelda (the first one).
• TES III Morrowind.
• TES V Skyrim.
• Doom (the original one).
• Half Life.
• Counter Strike (the original one).
• Ultima.
• Ultima Online.
• Dune (the RTS game).
• Warcraft.
• World of Warcraft.
• Age of Empires II, perhaps alongside the Definitive Edition.
• Sid Meier’s Civilisation (the first one).
• Final Fantasy (the first one).
• Chrono Trigger.
• Minecraft (as much as I hate it).
• Elite (the first one).
• Wing Commander Privateer Gold.
• 3D Space Cadet Pinball.
