Look back to Dracula. Sunlight has no effect on him, but his shapeshifting abilities are suppressed while *the sun is in the sky* (except for a short time at noon), even if he's inside. He loses this weakness while close to his grave.

So forget sunlight and make it about how the celestial bodies are aligned around them. In a tactical game, spaceships piloted by vampires could have a mechanic which buffs them for flanking enemies or moving into specific positions around the map.

I'm more curious how the "cannot cross running water" curse would translate into space travel, since in the novel Dracula couldn't even enter/exit a ship without assistance.

The coffin stuff lines up well with cryostasis though.
