To quote Khabib Nurmagomedov: "This is number one bullshit".
I understand that many games are not profitable even at the $60 price tag, but there's ways to make DLC enticing and desirable, price point and amount of content being the most important factors. Look at Fast Racing Neo, for only $5 you can get 8 new tracks, 10 new vehicles, and 18 music tracks. That's DLC done RIGHT, even more impressive, the developers are a small team delivering a high quality and polished game. These large studios are just greedy and ready to milk their fan bases (ahem Tales Of DLC).
