Games released for the ZX Spectrum in the early 1980's required patching. You had to find the problem and patch them yourself, in BASIC. There was no golden era of perfect games.
Didn't suggest there was - I only made the claim that there was a particularly rough era for PC in the second half of the nineties into the early 2000s, which I'll still happily stand by. In terms of personal experience, console gaming from the early 1990s through to the launch of the PS3 would be the only time I'd claim there was a golden age in gaming. I played hundreds of games across that period and cannot recall one problem. A lot of devs and publishers bad-mouth the QA that the platform holders enforced, but it made for a far, far more enjoyable experience than I had in PC gaming during that time.
Anyways, it's getting a little off-topic. I was addressing the suggestion that games in general were releasing more buggy now than ever before, which I don't think is the case. I'm not suggesting games are releasing less buggy now than ever before (and things in the console space have stepped back a fair way as well, although they still haven't dropped to PC levels, which have improved from their darkest days) but that there's no noticeable increase in bugginess (particularly on PC, which is where HoI4 is releasing - where it could be argued things have improved if we're looking at a longer-term timescale).
On the by, I love the ZX Spectrum reference
