Destiny: The Taken King, by Bungie.
For those of you who aren't aware, the fairly popular life-absorber Destiny recently released a new piece of DLC called "The Taken King." It was offered for $40 if you already own all the previous content (which would have cost you the base game price plus at least $35 for both DLCs), or $60 for everything included. Pretty sweet deal to jump in.
And if you were doing that, then it would be a great, very long game with a whole lot of content. However, if you're someone who, back in the day, bought the Dark Below DLC so you could play the extra stuff and enjoy the Knights of Crota, you're screwed. Or, similarly, if you purchased The House of Wolves DLC and wanted to actually fight wolves while patrolling, you're out of luck.
