I feel sympathy because they probably have to visit this forum every day and get flak from people who think it's still 1988 and PC games are released with no bugs
Wait, what? Did you actually play games around 1988? Games have always been buggy, however with the rise of the internet, patching has become much more common.
I remember buying games that had game breaking bugs where I could not continue without starting over. Where whatever caused the bug would continue to happen even if I backtracked and reloaded saved games. (Elder Scrolls: Arena, I'm glaring at you!) Restarting and reloading your last save was not an uncommon practice of games from that era. That often meant having to get out your manual or code wheel again for those old copy protections.
Though the history of game crashing was nowhere near exclusive to the Civ series, let me stroll down my memories of the former games.
I played the original Civ game. I had many crashes. I always tried to remember to save often. Sometimes I'd get the copy protection question wrong to restart the game... but usually I knew them. It took less time to guess than to find the manual though.
CivNet crashed even more often. The multiplayer was slow, unreliable, and made the game even more unstable than it already was without it. It ran under windows using the new graphics API that was the buggy grandfather of DirectX... WinG. On the plus side, this game taught me about TCP/IP ports, and how you had to have them open for some games... Port 1492.
I mostly skipped Civ 2... but Civ 3 certainly had it's share of bugginess...
Though, Civ 4 was probably the most buggy version of them all upon initial release. I imagine it was because it was the first with a 3D engine. I remember I frequently got video corruption that made all kinds of strange graphical defects appear in the game. Memory leaks would cause the game to become slower and slower over time, forcing you to have to stop and save the game, exit and restart the program.
I've honestly seen VERY few actual bugs in Civ V. I've had the game crash one time (which I don't know if that was the game's fault or not. I've seen a bug where in some occasions where Quick Save and Auto save features become bugged and each causes an unusual delay whenever they occur. Finally, I've seen a strange bug where the cursor becomes out of synch with the screen position that it's drawn, in some rare occasions where my output display was changed or re-detected by windows (as Windows *detects* my HDMI monitor/TV each time I turn it off and back on) when the game is in full screen windowed mode.
However, overall, it's been the least buggy version of Civ I've seen at launch. That's not to say that maybe some people have OS or hardware incompatibilities that might cause them problems, but it's been the smoothest for me.
But I digress heavily... the point is that I think people are really looking at the past with rose colored glasses if they think games were more stable 10 and 20 years ago than they are now, or that Civ 5 is more unstable than previous versions.
