Irrational Games, the developer of BioShock and BioShock Infinite, are going in a dramatic new direction. It appears that they are keeping just a select group of people to focus on smaller games made by a small group of people like they were originally.

A letter was written by Irrational Games’ Founder and Creative Director Ken Levine, explaining the huge change and the reason for it: “While I’m deeply proud of what we’ve accomplished together,” Levine wrote, in part, “my passion has turned to making a different kind of game than we’ve done before. To meet the challenge ahead, I need to refocus my energy on a smaller team with a flatter structure and a more direct relationship with gamers. In many ways, it will be a return to how we started: a small team making games for the core gaming audience.”

He goes on to say that they are “winding down Irrational Games as know it. I’ll be starting a smaller, more entrepreneurial endeavor at Take-Two. That is going to mean parting ways with all but about fifteen members of the Irrational team. There’s no great way to lay people off, and our first concern is to make sure that the people who are leaving have as much support as we can give them during this transition.”

Levine then discussed where they will be headed for in the future, saying, “To make narrative-driven games for the core gamer that are highly replayable. To foster the most direct relationship with our fans possible, we will focus exclusively on content delivered digitally.”
