Shivering Isles took forever to come out too..... - The fact is if DLC comes out too soon, gamers
complain 1. it should of been on the disc; 2. It must of been cut out for it to be ready so fast.
and if it takes "too long" your response is seen.
I think the difference is some devs will have whole sandboxes and development enviroments which allow for the creation of content easily and quickly - we know this is the fact for skyrim / fallout games as they then go onto release parts of these SDK's to the PC user community anyway. As these have been created already it massively shortens the time to produce good quality DLC if you already know what your wanting to create.
However, to those who say "it should of been in the original game because theres a path/bridge/road/quest/random NPC who mentions it/symbol on the ground/weird sound you here/some textures in the original game....." how many games must there be that had these "link" points into DLC, for DLC that never arrived? Just because a dev made sure they had some explanation for how some DLC links into your main game doesn't mean the DLC should of been on the disc. It simply means they planned ahead and thought of you as a gamer, who wants the immersion breaking experience that some DLC offers where it infact is unconnected completely to the main game?
Yes - Some developers take the mick with DLC. They do
cut stuff out of the main game / story, and the only way to stop this is vote with your feet/money.
