I mention DLC and Mods because people still want to play with the shell of a given game, even if it isn't MQ related. Playing after completing is sorta like that. Saying, its over. But I still want to keep playing, without necessarily starting a whole new campaign. I would think that playing after the MQ and thouroughly being able to witness first hand how the choices you made affected the world would be much more rewarding thatn a still and a one liner that covers each faction encountered. If those choices do actually mean something, then there is a lot of depth that cannot be covered by a brief summary. If the world ended up completely different after each playthorugh (not just as a result of the coices at the end game, but throughout) the I would replay the hell out of that game.
^This… Couldn't have said it any better myself.
Yes it's more work for Bethesda, but what the hell do we pay them for anyways? To make great vidya games, that's what we pay them for.
And creating varying Worlds after the Main Quest(s) doesn't sound like I'm asking too much.
Now if they can find goals to reach after the main quest is through, then I would applaud them for 20 straight minutes. Not literally.
For instance, they could open up new options for the player after the main quest is done like building a town, fixing politics, having a family, more cyborg implants, more enemies, new random encounters that trigger after the main quest. This is to encourage a deeper storyline from them and in turn encourages us to keep playing long after the main quest is through.
Or one idea is where your character ages, ages and you have to find an occupation in the wasteland just for kicks and roleplaying.
You're old and maybe you're a fisherman, NPC's will seek you out for guidance and you can teach them what you've learned.
Or you become a doctor and help people out, give special people implants for a price.
Or you're an old gunsmith, the only guy that can make certain weapons for people.
Or you, yourself becomes a companion to someone else on their own quest. If you choose to help them in your old age.
Maybe at a certain age, you die, and the end… but if you had a child, based on your character's look, your game transfers to the child and grows up seeing the impact of his father.
Maybe they won't go that deep, but they can do something like this.
Bethesda should really be reading the Fallout sections, we has the best ideas and it's ALL FREE.
