Nice to see SimCity 3000 on there. I know 4 is more feature complete. Especially with all the mods available for it. But there's a certain atmosphere to 3000 that I just enjoy more.
Fun fact SimCity 3000 wasn't even playable for a few years because the DRM was so invasive that Windows blocked it as a security threat.
Doing some searching online it seems the claim normally made is that all steel rivets wouldn't have prevented the sinking but could have slowed it enough to allow more passengers to be rescued.
To provide a bit more context lower grade iron rivets were used because of supply shortages at the time. Higher quality steel rivets were still used for the midsection of the boat with iron rivets being used on the ends.
