What about the Great Khans, King, Fiends, Vault 19 Powder Gangers? What if I wiped them all out? What if I didn't? How are the Devs going to reflect that in a DLC? Again the "NCR DLC" as an example. If you don't deal with the Vault 19 PG and Fiends they stay around for years giving NCR a hard time. If you deal with them then NCR has an easy time. How would the Devs be able to relect those changes into the"NCR DLC"
What about the "Yes Man DLC" where I am asked about all the Factions I want to keep or remove? How would they relect that? What if I keep the White Glove people but did not keep them from eating people?
Way to many variables to account for, so much is interconnected.
Perhaps I'm missing something here but I honestly don't see the issue. Ok take the NCR dlc, if you don't deal with the fiends/PG's the quests will still be there when you come back from the dam, if you deal with them, they'll say the same thing they do if you deal with them before the dam.. Why would the DLC have to change much of this?
The DLC, well imo anyways would really not have to change much apart from a legion DLC (much more burning things and spiked heads..) They would add NEW quests, characters and possible locations as well as letting you play just as you did before the dam..
I don't see the issue here?
