A shame that the end result was a kind of a meh character. I mean, Ulysses's journey was far more interesting than himself, which kind of sucks.
Honestly Ulysses would have been much better served as the Legion companion in the base game.
I may have told you about this idea I had for Ulysses if it had been possible to implement it.
Basically Ulysses would become available as a companion character in the main game, being located at the Wolfhorn Ranch. Alternatively the player would keep running into Ulysses at certain points of the main campaign similar to Victor. The idea would be that Ulysses would be observing the player and the decisions he or she would make for certain locations and which groups and factions they would support, these would all factor into Ulysses' decisions on his own objective.
At the end of the second battle of Hoover Dam, rather than the game ending after the battle, Ulysses through ED-E would talk to the player, telling the player that he was the courier first chosen to carry the platinum chip until he saw that the player was next in line for the job and because of that declined the job (same reasons as mentioned in Lonesome Road).
Now that the second battle of Hoover Dam is over and the player has survived the battle, Ulysses calls the player to come to the Divide (which would now be unlocked) where Ulysses will be waiting for him or her and where the player must defend the decisions they made on who to help and support as otherwise Ulysses will wipe the slate clean.
Basically Lonesome Road would be the real ending of FNV and the player must finish it in order to see the epilogue screens.
Some of the problems with my idea is that it would require Ulysses to be made into an un-killable character, something I would rather not resort to. Ulysses would have to be retro actively inserted into the campaign, he would not be available as a companion during the second battle of Hoover Dam. ED-E would either have to be the player's companion during the battle, or would have to just show up so that Ulysses could talk through it. ED-E would have to be a companion that joins the player when they go to the Divide, the original ED-E actually carrying the detonator needed to launch the Divide's ICBMs.
One issue I could see with the idea is that people would not like it that they can not play the DLC until after they have finished the main campaign.
Technically this would also really be so difficult to pull off that it would have to be planned in advance.
To the OP's question;
So yeah, what do you guys think? Do you think it was cool for Obsidian do this?(Unlike the Fallout 3 or 4 where all the DLCs were completely separate, basically anthologies.) Or was it a stupid concept to begin with?
Yes, I really liked that the DLCs were interconnected and told a separate storyline that ran through the other storylines. And like you mentioned, it works really well when the player plays the DLCs in the order of the release.
I have some criticisms on the DLC's content itself but not this idea of interconnected-ness.
If anything it only made me feel how utterly random the DLCs by Bethesda were for Fallout 3 and 4 and how little to no connection they had with the main campaign. They have actually made me develop somewhat of a dislike for DLC as I would much rather have more content added to the base game and its campaign instead.
