Arani Korden said:I haven't read any Star Frontiers material in years, but I do clearly remember equipment specially designed for Vrusk hands. IIRC, the pistols had a sort of ball-shaped grip.
Nothing in the rules about it, other than a couple of illustrations showing Vrusk holding ball gripped pistols. There's also an illustration of one using a normal grip. Really they shouldn't have any problem with normal weapons, nor should humans (or Yazarians) have any problems with using a ball grip. The armor bit does make sense as it would for drasalites or Yazarians (the gliding flap would get in the way of human armor), so the rule should apply to any race really.
Other points of difference (besides the ones trancejeremy mentions) include giving Drasalites and Vrusk dark vision (huh?). Vrusk losing their comprehension ability (a bonus to diplomacy and sense motive would have been fine here). Vrusk carapice having value as armor. And the Yazarian life enemy being reduced to a combat ability (in the SF game it was a purely role playing note and it included an example of a Yazarian scientist making a disease his life enemy).
