Star Wars: The Old Republic: Possible Playable Races, Part Two has slapped up the second half of their speculative feature on the potential races that will be inhabiting BioWare's Star Wars: The Old Republic. Personally, I think mandalorians are a given:
Mandalorians hardly need an introduction, but for the few of you out there who are somehow unfamiliar with these guys the Mandalorians are a warlike people who don't necessarily consist strictly of humans, but are instead comprised of many races. The Mandalorians are ruled by a single ruler known as the Mandalore, and have a long history aligning with the Sith Empire. Mandalorians are responsible for a great many conquests, decimating entire planets, and races, all in the name of glory and honor. They are also known for being sell-swords, serving as exceptional bounty hunters (a'la Jango Fett) and mercenaries (Canderous Ordo).

Why we like them: Boba Fett, Jango Fett, Canderous Ordo, the notable Mandalorian characters simply exude badass. The (race) is so steeped in lore and history, and its significance in the Star Wars ethos is so far reaching across all the various time periods, that there is simply little reason not to want to include them. Even when the Mandalorians were all but extinct, Boba Fett won our hearts in minds in the original trilogy, short screen time, limited dialogue and all.

Likelihood of making it in: This is a tough one. The Mandalorians are a race, in a sense, but could almost be considered more of a faction. As we mentioned earlier, they are comprised of many different races, though we mostly know the Mandalorians as being humans. I think Bioware could get away with making them a race made up only of humans, and they'd be a shoe-in in that regard. One snag though is the fact they would have to be restricted to the Sith Empire, and we've not heard either way if there will be any race restrictions either by class or faction. This one is a toss-up.
