Some people have already beaten multiple Elden Ring Nightreign bosses, or indeed the entire game, totally solo. It is perfectly playable alone. But I agree with Will's Elden Ring Nightreign review: it is miserable alone.
My god, Nightreign is so much better with friends. Granted, in my experience shoveling thousands of pounds of mulch on a humid summer day is also much better with friends. Everything is. The friend buff is real. But the gulf between the solo and team experience in Nightreign is so massive, from coordinating abilities to sharing loot to managing aggro, that it's got me thinking about the merits of explicitly building your game with teams of three in mind, especially when you have limited in-game communication and no crossplay. Betting your game's experience on the player's ability to recruit two friends feels like a mistake.
