Games are bundles of licenses themselves. That music costs money, as do other assets and sometimes engines. And over time some of those licenses can expire or require renegotiation. Sometimes it's easier to just stop selling something than figure all that out.

Because this is a billion dollar corporation and those typically hire cutthroat teams that negotiate with other cutthroat companies. I recently tried licensing a 50-year-old unaired raw video from a news corporation. It's in the range of $5-10k. We're talking b-roll with dead air and such.. big companies aren't interested in this stuff
