It is a very different world and economic climate in the gaming industry today than back in the days. Back then you more or less were forced to release a game with no bugs because there very very limited ways of updating them after release. You had to make new CD-ROMS for example. Very costly. If you had a bug you just had to live with it. Slim chance to get an update out quickly. Buying a game back then was a much higher risk than today and the games cost about the same as today. Some might even be cheaper today than before. But the consumers also did not know about a certain game until it was ready for release and you only heard about them through a magazine or maybe a TV show. There were no Internet (as we know it today), no YouTube to advertise the game etc. Unless you were a big developer or a brilliant person (Chris Sawyer) you had no chance to survive in the gaming industry. Today news about games are leaked (or released on purpose) long before a game is finished. With platforms like Steam even a tiny 2 person company can get their games out there for next to nothing compared to how it used to work. Now they are "forced", in many ways by us the consumers, to release early to undercut the competition or to stay relevant as a company (survival). It doesn't always work but just see what happened with RCTW. PlanCo was a hell of a lot more refined and finished game at release than RCTW ever became. But Atari saw that they were losing towards PlanCo and were forced to release early or all the customers would have gone to Frontier (which they eventually did do). So we, the consumers as a whole, not just for this game, has created this way of release cycles long time ago. Even the mamoths in the software industry, Microsoft, Apple, Adobe etc. have stopped releasing new versions, they just released updates to the existing ones. In many of those cases, like Adobe and Microsoft, you still have to pay a monthly or yearly subscription fee. Same thinking with the "Season Pass" feature a lot of games, mainly FPS and bigger AAA releases. You as a consumer either pay a subscription fee and get access to whatever new content they decide to release (not always known upfront what it will be and how much). This is the economy of the gaming industry today. The past is in the past, we need to move on shape the future. It was not always better in the past. Certainly not in the gaming industry world.
I mean... that was quite a long time ago. Talking like... 15 years ago maybe? For PC games at least. There were patches coming out for games a long time ago, even for RCT3 they had patches coming out. Of course they couldn't be as huge as they can be now due to internet speeds, but they could at least fix bugs and stuff via downloadable patches.
I also don't think that anyone is arguing about whether things were better in the past or not, it's more of a fact that companies released full games back in the day, whereas now games seem to be a work in progress even after release - and not just bug-wise but also content-wise. Whether that's a good or a bad thing is another discussion, but the fact is that you can't count updates coming out as being a bonus or a gift from developers, when all they actually are is a means of completing the game.
