alt Hacker NewsHardcover books often contain typos. The Kindle versions of these books will sometimes get updated to fix these typos. These updates make the reading experience better for Kindle customers, but they do not reduce the reading experience for hardcover customers. Your hardcover book will remain just as good as it was at the time it was published.
Now, Terraria received much more significant updates. I think a game like Terraria is fundamentally incompatible with the idea of physical games.
It seems we're largely on the same page. I would point out though, sometimes those seemingly minor tweaks can be pretty important; they're not always at the level of typos in a book.
One that affected me personally was in Pokemon XY, where if you saved in the wrong spot it would corrupt your entire save. As a kid it was a pretty memorable experience to lose ~20 hours of playtime on my Christmas present because I assumed the updates weren't important. Granted, day-one bugs that major in first party Nintendo games are rare, but it's not a given that they're irrelevant either. It can go either way.
