Mangrea

Mangrea is a setting so cyberpunk it could only exist in orbit around a gas giant pulsing with neon colors. The worlds and stations that orbit the enormous planet are full of mysteries and opportunities for adventure, with allies and enemies abounding in equal measure. It could be used for courtly intrigue, it could be used for deep examinations of the impact of technology on human society, it could be used for romance among the stars... but it's mostly used for big fights with lots of explosions. This is fine.
