The only time it would matter is for popular characters across multiple games, like Master Chief/Drake etc. In nearly all cases there's plenty of voice actors who could fill the role, and I've not seen people sell a video game by advertising voice actors much outside of Liam neeson in fallout 3 and Patrick Stewart/Sean Bean in Oblivion, none of which are primarily voice actors.
