For me personally open world games don't need a good story at all. I'd rather have a good story with more linear narrative focused games.
I want my open world games to have fun and rewarding exploration with a good loot system and fun sidequests.
If for exapmple RDR2's story was half as good and that 50% of pure quality was pumped into the missions and gameplay, I would have had a much better time with the game.
Most people will be expecting a decent story from days gone.
For me mission story and variety go hand in hand. For example in RDR2 most of the mission had a purpose directly tied into the story, you had to Rob to support the gang, go fishing with John's son, steal something for a mission, there are tons more examples with very unique gameplay scenarios like pretending to be high class and win a card game on a ferry casino, scaring a guy by hanging him of the side of a boat in a Croc pond etc
What I hate are tedious loot, kill or fetch quests with shoddy context, where you have to do a lot of these very tedious simple tasks in order to progress.
I am concerned that in some gameplay of days gone you are at a camp and a guy who is an authority of the camp says you have "salvage the salvage" and after he says you got to start doing runs for him where drifters have been causing trouble for his supply routes and u have go to a radio tower where the drifters have taken over, it sounds very much like you got to go to the drifters, kill them, steal there shit and report back to the camp leader.
He says it 48.35 in this vid
It is good that there is context, that you are retrieving the things that Leon stole l, but the runs do sound like very filler ish, and not the most exciting mission type, a bit like in fallout games "these raiders have been causing bother for me at the power plant etc"
I hope these type of "runs" are either more carried then they sound or there's not a lot of them in the game.
