For all you wanna-be-future-developers and/or gaming executives out there, the best thing you can do at this point in preparation is familiarize yourself as much as you can with failure.
And one of the best ways to do that is read interviews in which developers of massively popular and success game franchises talk about the failures they've encountered during their careers, what caused them, how they overcame them and what they learned as a result.
Turns out Gamasutra has a great article that very much speaks to this idea. It's an interview with Flagship co-founder, and ex-Blizzard bigwig, Bill Roper in which he goes into tremendous detail about the trials, tribulations, sacrifices and lessons learned during the turbulent times that led up to Flagship's closing and the role that the company's action-RPG Hellgate: London played in the whole mess.
