alquist_walter: I heard that they introduced a lot of bugs in BG.
I heard the same, I also heard they've been fixed but I never felt like shelling out the cash to find out for myself. I am quite content with the classic versions
alquist_walter: It was so bad? Maybe I was lucky with the games I bought then, because I can't remember a title that tried to leech money, like you can see today, in pay-to-win games for example.
Sometimes it could be. Heroes of Might and Magic 4 is an extreme example. The base game shipped without multiplayer. If you tried to start a multiplayer game, you'd get a message saying the feature haden't been added yet. sometimes the game crashed after a battle. These problems were fixed in the first expansion, but of course, you had to buy the expansion to get the fixes. The second expansion was about as cliched and blatant money grabby as it got so don't get me started on that one :)
Doom had several expansions (lots of unofficial ones too) that were of course, a cash in on the Doom name. Several popular games had this problem. Baldur's Gate: Tales of the Sword coast didn't add much, just a new dungeon and a few items really. Icewind Dale: Heart of Winter was really really REALLY short, hence why Trials of the Luremaster was offered as a free download.
Quake 2 had 3 expansions, I had 2 but they were simply more of the same. They weren't worth what I paid for them (just over half of the base game IIRC).
Instead of paying just over half for the same game at once, you are now being "nickel and dimed to death" through cheaper but more numerous DLCs. While the method is different, the concept is entirely the same. Not sure if that's worse or not.
There was also an complaint about game manuals, not just expansions. Before, the manuals were actually good to read, but in the late 90's manuals became thinner and thinner, why? Because all the good info was put into strategy guides that were available for separate purchase. Fortunately, now you can just hop online to find a walkthrough, don't need to buy them.
EDIT: Back in the 90's, not everyone had internet access so if game needed patching, it wasn't just a case of downloading it. Sometimes expansions packs were the patch along with extra content
