Well, a little bit of ‘yes’ and a little bit of ‘no’.
If it is possible over the course of the game for turn orders to be changed, or for a player to choose to draw a card, or cause another player to draw a card, then it matters in a way.
If I can cause actions to make another player draw a card, then it is more meaningful if the deck is shuffled already, because the card that I caused the player to draw is the same as the card I would have drawn if I drawn a card instead. However, from the perspective of the user, there is no way for them to know the difference.
I feel like it is better for the integrity of the game if the deck is shuffled for real, though. Because if ever a user finds out that it doesn’t work how it is expected, then it cheapens the experience in a way. Kind of like how the old Mario Party games determined the outcome of dice rolls when the die appeared on screen instead of when you pressed the button to ‘roll’ them.
It appears to be a “V” Devic actually.
That didn’t help at all though.
