Yes but they also sell vastly more copies and since a lot of it is digital there isnt any overhead so overall game companies make more money today than they did years ago.
Not sure if that's enough to offset the huge amount of resources now required to develop and market a major title.
According to my video game developer relative, who's worked with nearly all the major gaming companies, today's big games require huge teams and a lot more time to produce than they once did, to the point where the pool of talent becomes a limiting factor.
There's only so many people with a really effective skillset and hiring and retaining them long enough to complete a title is a big issue.
I've got several of the DLC planes in Rise of Flight and BoS and DCS
