Wait, what...? When I replayed it, I didn't see all that much different in the museum... Did they actually change anything?

@Matthue_Loose according to the wiki, the Steam version replaces all the copyrighted references with something similar but legally distinct, like replacing the pokeball with the "goodball" or the portal gun with the "wormhole rifle". Usually still obvious what it's referencing, but I would also imagine all the ripped sound effects from like Zelda and Smash get replaced too which I can't see as anything but a downgrade for something like this
