This is a pretty solid list, but I’d try to bridge the gaps between older games and more modern ones, to show how things progressed. Essentially, you want each section of the museum to tell a story about how some critical building block of gaming was taken from concept to implementation.

I would actually include both the original Castlevania and Metroid then follow it up with Symphony of the Night. Show the original Castlevania game to establish the series, then show Metroid which has the exploration and backtracking with new abilities. Then show SOTN, which shows the combination of the two (effectively cementing the entire Metroidvania genre). Then show a game like Hollow Knight or Ori and the Blind Forest, which goes on to embody the genre several decades after it has been established.

Zelda is a good one, and I’d follow it up with something like Okami, which follows the same dungeon formula in a radically different setting and art style. Again, showing the genre’s establishment, then showing how it can be adapted.

For Final Fantasy, I’d also include FFX, which follows a very similar turn-based playstyle. Maybe include a Dragon Quest game somewhere in there too, as that series tends to stick to the same basic gameplay formula. Then I’d take it in a different direction and show something like Bravely Default, which is still technically turn-based, but also has additional elements layered on top.

I’d chase Super Mario 64 with something like A Hat In Time. Again, showing the establishment of the 3D platformer, then showing the elements in use elsewhere.

You have Ultima on here, which I agree with. But I’d probably break the display for it into two different halves: For the RPG half, I would include some more tabletop-inspired games here too, as the early game devs were largely tabletop game fans who were simply adapting their favorite games into digital settings. Games like Fallout 1/2, or Baldurs Gate. Maybe even show a modern game like Baldur’s Gate 3, to show how tabletop RPG mechanics can gracefully transition to digital games. Morrowind would also fit nicely here, but Skyrim is a little too far removed from old TTRPGs to be relevant to this section. Still important to have on the list, but I’d probably have it in a section dedicated to player-made mods.

For Ultima’s one-point-perspective dungeon-crawling, following it up with something like Persona Q or SMT: Strange Journey could be impactful to show how it was adapted to more modern games.
