In a sense, Arkane already has a sort of Groundhog Day-type of game in their portfolio with Prey: Mooncrash. Clearly, that and Deathloop appear to have significant differences, but Mooncrash may have served as something of an inspiration for this. Maybe not... Since Prey and all three of the Dishonored games and DLC provided quite a bit of good entertainment for me, I'm hoping this would prove to be a similar experience. But, I must agree with Damien_Azreal's reservation about any sort of mandatory PVP aspect. I'd prefer not to have, say, an hour and 20 minutes of immersive single-player game-play suddenly go sideways with some stranger crashin' the party. So, for me, that "multiplayer invasion element" really does need to be "completely optional."
