Of course they can.
The vision driving Divinity:Original Sin has been that every feature which is in there has real gameplay value and isn�t a gimmick."
I think the guys at Larian are really really tired, it shows on their faces. Especially David didn't look so well. I am sort of concerned about them. I guess they are closing those 24 hours a day schedules...
However.
And maybe this could mean opening another thread. But what are people expecting from a day/night cycle ? (Not NPC shcedules...)
What does Night/Darkness (for deep, ligthless dungeons...) change compared to Day ?
For me, I would reduce the vision variable. Alot. At least. Already a huge impact.
Then, make sure there is a proper lighting system at night, (either at night or in deep lightless dungeons, so this must exist already). You know, light spells, torch, night vision, Sense Life spells, whatever.
Just with these two things, you have gameplay/immersion impact on the game.
Then, Other night thingies would be a boon (various day/night bonus, night monsters, and so on...), but not required in the beginning.
Please do not tell me D/N doesn't have the potential to have a real gameplay value. Well, actually, it would have the gameplay value the devs give it (just like a charisma or intelligence or willpower stat, it is utterly useless if devs don't make it usefull, but this is another subject). Sometimes, I am confused with the logic behind DOS.
Or DOS is not a realistic RPG, it is an open choice freedom RPG, and I am mistaken. But then, so many things try to be realistic, that this would be really confusing.
