Gil Brodie: A Game of Poker
A minor side quest for a minor character.
Talk with Gil aboard the Tempest, and he'll eventually (sometime after settling Podromos) challenge you to a game of poker by email. Meet him in the Vortex, but don't expect any minigames. Instead, your only real choice to whether to cheat by using SAM, (a guaranteed win) or rely on your own skill (a guaranteed loss). Either way, you can also choose to flirt with Gil, if you're his type.
Walk away when the game's done to complete the mission.
