Heres a odd idea why not add a mini games that has a racing game similar to starwars pod-racers or something just SWTOR version for players who want to earn some extra credits but also want a fun little game. If you have a need for speed and danger perhaps this is your vice.
However for the gambling type why not add a two player Pazaak mini-game similar to the one from KOTOR to add a little bit of change between the chop, slash kill repeat. And plus put bets on who would win, who ever makes the best kind of deck rules the card games side of SWTOR.
