We have an in-game casino in Nar Shadda, and yet the developers haven't managed to implement some form of mini games revolving around this casino. I think it's about time to make use of this scenery.
There should be tons of action and tension going on around this place, and players should be able to put all our hard earned credits on red or black at the roulette, card games (poker, black jack), board games (chess, checkers, backgammon) one armed bandits/slot machines, hey even betting on twi'lek slave girls mud wrestling could be added to the fun.
A casino is a stage for both PvP gambling (poker, chess, backgammon) and PvE (traditional casino games) with in-game credits, with the risk of cheaters (people using chess computers etc) who can be shot on sight.
Just my 2 credits!
