On this day back in 1991, a little four-man PC game development house was born, and you may have heard of it. It’s called id Software and they were making waves in the shareware market with games about an adventurous little kid called “Commander Keen”. They’ve come a long way since with their Wolfenstein, DOOM and Quake games and have changed the face of gaming forever. They started out with just four members, and today, only two original staffers are still there. The office has grown in leaps and bounds over the past few years and they now boast a staff roster of over 100 talented members working on a few “AAA” titles at once. The other big thing this year is that this is the first anniversary where id Software is no longer a privately owned entity since the buyout by Zenimax. A lot of things have changed over the years, but they’re still id Software and they still make the games that drive many people’s dreams, including mine. So happy birthday id Software, and may you have many, many more!
