Games can 100% live on without DLC. Destiny has already made their money because of the hype. You only mention Halo 3 and forgetting that Halo 1 and 2 did just fine without it. Companies like the now Bungie are becoming nothing but money hungry and it's showing in their lack of content and story. It has been a 10 year project and it feels like they have barely spent a couple of years in it. Due to this it's absolutely my right to complain.
