is it possible add day and night cycle in game ?

I can remember that modders were able to do this trick for DAO. Return to Korcari wilds mod has it shift from day to night, so I hoped the same could be done in other games, but maybe frostbite is too tough to work with. It seems that the modder in DAO just switched the sky and all the lighting and textures automatically switched to match. Also, a daytime mod for the camp in Origins, where you sleep and wake up to the morning, so at least it was possible in that earlier game.

It would be incredible if someone would work out a way in MEA and Inquisition, just to spice things up and keep it from going stale at 300 plus hours.

For me at least, I would like to see change if the scene dictates it. Otherwise, like Fallout 4, it didn't really change anything. My sneak skill is stay the same as daylight. In State of Decay, nighttime means reduced visibility and Ferals will end your night jaunt. It's more important to me that the world or worlds are bending to my will as a player. Outposts should evolve somehow. I shouldn't be running into respawns. There has to be tangible changes otherwise, it's a checklist quest that didn't do much to alter the world.

I think they can but for MEA it wouldn't feel necessary. Then again if it included weather cycles it could make things interesting.

Now weather effects would've been cool. Dust storms on Eos as a hazard? That would've been fitting.
