I don't know if anyone noticed this yet but Adam Lazarre-White who played Zero in Wing Commander Prophecy and Secret Ops is Jacob Taylor in Mass Effect 2 one of the main characters in the game for those who haven't played it.
I've got a question about this: Is he a voice-actor in Mass Effect 2 or does he actually appear in live-action footage? I only know that game from hearsay, so I don't know whether it includes live-action footage. (Today's games usually seem to have cutscenes in the game engine instead of seperate live-action or pre-rendered scenes.)
If he is just doing voice-overs, is his character's appearance modelled after how the voice actor looks? You know, they sometimes do that, think of Tolwyn in Wing Commander Academy or Xanatos in Gargoyles.
I don't know or care too much about Mass Effect (other than it's infamous for some sordid in-game scenes), but I'm fairly certain the cast are used for their voice talents. Aside from Command & Conquer, I don't think there have been many recent games featuring FMV.
