'A Challenge to Grow'

"Space Invaders," the classic arcade game, poses a challenge to Libin because conference rooms on each floor of its headquarters are named alphabetically after video games. There's the "Asteroids" room on the first floor near the cafeteria, and "Donkey Kong" and "Defender" on the fourth floor.

"To get to Space Invaders, we need to get to floor S," Libin said. "Whatever letter in the alphabet S is, we need to have that many floors to get there."
