Chris Judge from Stargate did the same. That dude is in a lot of video games.
Kate Mulgrew was a very distinctive voice. I heard it right away in Dragon Age Origin.
Patrick Stewart also has a great voice in Elder Scrolls Oblivion.
The first person from Trek I remember hearing in a game was Leonard Nimoy in Civilization.
Star Trek actors are the most robust actors. They’re everywhere. I watched all of Boston Legal without realizing it wasn’t Star Trek. Our boy Frakes plays adult Finn in the adventure time episode Puoy, George plays Ricardio. You can’t escape it. Star Trek encompasses all.
Edit: sort of unnecessary edit but when I use actors here it is gender neutral.
Ensign Ro and old Jake are both in Half-Life 2, those voices are ingrained in my memory so I instantly recognized them when i watched the show.
It’s especially great when they do something that’s completely off the walls crazy. Michael Dorn played a screaming dwarf in the Billy and Mandy episode “Here There Be Dwarves,” who went mad after centuries of mushroom farming and exacted his revenge by invading the Keebler elves’ hollow tree. Then R. Lee Ermey pops up to censor the carnage and the dwarves and elves compromise by making mushroom cookies, and Billy does karaoke. That show was so delightfully warped and random sometimes.
