Similarly, Gaider also originally wanted to have Mal's actor Nathan Fillion voice the character, but decided against it as he would have had to perform an English accent. However, Gaider was still pleased with Valentine's voicing.

In an interview with GameZone, David Gaider said that Alistair was a bit of a "woo-bie" and that his romance was "very cute". However, Gaider said that he wouldn't want to have another Alistair-like romance in the interest of originality.
