Both tell a story about betrayal from a close fake friend resulting in a life thretening situation. In Gankutsuou Dantes was betrayed and sent of prison out of jealousy and Shin, (main character of Area 88) and sent to war with low survival rates by a mean trick. Also, both stories contain a woman as a reason for betrayal. Difference: Area 88 isn't concentrated on revenge as much as Gankutsuou.
