I really like Pazaack. Granted, there are some glitches with some of the players, and the rewards aren't amazing (Suvam's discount is nice though...), but I find it to be a nice distraction during gameplay.
I do agree however, the game in not entirely fair in KotOR 1. Too many times I lost because the computer constantly gets twenty w/o using a hand card. KotOR 2 did seem to address these issues however.
It's too bad you can't get Zaalbar to play pazaak for you. Maybe the AI would not cheat then.
Han: Let him have it. It's not wise to upset a Wookiee. C-3PO: But sir, nobody worries about upsetting a droid. Han: That's cause droids don't pull people's arms out of their sockets when they lose. Wookiees have been known to do that. C-3PO: I see your point, sir. I suggest a new strategy, R2. Let the Wookiee win.
