A usability article by Peter Seebach at IBM developerWorks suggests that we ought to pay more attention to video game interfaces when designing programs for business and other everyday users.

Game developers know that their audience will walk if a program is unusable, so they tend to produce programs that are -- compared to most productivity software -- paragons of stability, convenience, and user control. If productivity software developers made the same kind of effort, users would spend a lot less time cursing the names of the vendors they're stuck with.

Among the things Seebach suggests we look to games for are: streamlining, reliability, approachability and adaptability.
