Should the game has choice base quest for both main and side?

I just wanna know if the game should have more choice base quest for both main and side quest like other games or it should be linear?

You mean like having choices that affect the outcomes of quests or having more side quests unrelated to the main story? If it’s the former, I wouldn’t be against having choices, but I don’t think it’s something whose absence would break the game either.

in both ways, because it seems like the choices can make the game more personal in story telling. and it could be use as a side quest too like, one of the quest will be you have to choose between saving a person or get him killed but a mass number of people from plague will be saved. so depending on the choice we will see that the base will have more people or that specific person will live and will give you new item but many of the shops will increase their prices of items. its just an example
