Joining late, so I'll weigh in on the previous questions. Note that my answers reflect my idea of a typical samurai. There are always exceptions. An adept street sam might substitute magic for chrome and still be a samurai in all the ways that matter, but I wouldn't consider them typical.
(1) Which weapon? A smartgun and a blade. The katana is traditional, but retractable spurs are nice, too.
(2) Which metatype? Any. The original Street Samurai Catalog showed us how samurai can be all shapes and sizes. If I had to pick one for the archetype, I guess I'd go with "human," if only because there are more of them.
(3) Which augmentations? An Initiative booster and a smartlink are the bare essentials, but street samurai ought to embrace augmentation more than most. Cyberlimbs are certainly popular, but not required.
(4) Which code? The modern notion of a samurai is basically a "bad-ass warrior who is loyal to the death." Whether or not this is historically accurate is irrelevant. Street samurai are born from popular perception, not history. Further, street samurai are not feudal samurai. According to the new bushido, street samurai owe absolute loyalty to a contract, not a person. Essentially, street samurai always do what they say, no matter how complicated or convoluted a mission turns out to be. It's not about the nuyen, it's about the word. A mercenary can be bought by a higher bidder. A razorpunk can get bored or distracted. But a street samurai is relentless and unyielding. Integrity is the defining quality of a street samurai. In a way, this is the cornerstone of shadowrunner ethics in general. Shadowrunners -- most especially street samurai -- are expected to fulfill the terms of their contract with Mr. Johnson, no matter what. Of course, after the job is done, it's time for a whole new deal.
(5) Which priorities? Resources, then Attributes, then Skills.
