I'd suggest "Strauss", based on the fact that Strauss Zelnick was CEO of Crystal Dynamics, publisher of 3DO SC2, at the time it was being developed (although he seems to have resigned before the release).
They bowed to me, but I bade them stand. They cheered to me, but I made them silent. They fought for me and I bade them peace. They died for me, and I am content.
I'm starting to feel "Robert" is the one true choice. Even if the last name is a reference to the Crystal Dynamics CEO, it makes more sense if the captain has a different first name, anyway. You could leave "Strauss" in as an embarrassing middle name (after his great-great-great-great-grandfather or some closer ancestor named after him) or something, if you want to keep the Zelnick family reference intact.
