Always sad to see a game getting delisted. But props to the devs to notify us about half a year in advance. Usually these delistings are instant without notification and then its too late for people who want to buy it. Now the game is at a good discount, 80%. If I had interest into the game and there was no FH5 on Steam, then I'd buy it.
Licensing issues with music can easily be patched out and replaced by other music. But what can they do about the cars? I guess a lifetime license for the games is too expensive, so it will be a limited license and then the delisting is only matter of time. Man this sucks.
