No, in those days you'd be lucky to get half that...notable games anyway. More than today yes, but look at the bigger picture and see the immense amount of work & resources that go into just an average console game today, never mind PC games.
did you actually play games back then? loads of work went into old games these days its like people leave out features because they can add them in dlc or an expansion its very rare for a modern game to feel "complete" which gets on my nerves no end.
sometimes half the bloody files for the dlc ir not more are already on the disc long before the dlc is released
