Seconded. As someone who plays a fair amount of First Person Shooter games, I can tell you that there are all types of games and all types of players. The popular Call of Duty games are pretty good examples of life-wasting time sinks. They require little skill and less strategy. However, the recently released Halo: Reach is a deep game with satisfying multiplayer combat that continues to surprise me as I progress in skill. Anyone who is interested in competition and outside the box thinking should definitely take up playing games online. They require speed, accuracy, strategy, teamwork and most of all creativity.
Many of us enjoy expressing ourselves through electronic games. As such, I feel that this aspect of our lives should be shared among our fellow gamers in the LessWrong community.
Video games are a great way to reduce compartmentalization and learn real-world rationality skills. Indeed, what brings us together at LessWrong can often be our love of games; someone in the LessWrong community without this advantage might find learning rationality difficult. In this light, outreach into the transhumanist/rationalist community to promote gaming is low-hanging fruit for serving the future of humanity.
Please consider this post a unique opportunity to begin discussion of this important issue and facilitate further debate in the near future.
