Great profile on Tim Sweeney from Stephen Totilo. Again, part of my childhood gaming, especially ZZT, which was a brilliant editor and one of the first play/create tools I messed around with. Striking to see how much impact the shareware creators of my youth - Carmack, Sweeney, and all the Apogee/id/Epic crews - have gone on to have in the modern industry. Also: striking to be reminded how much of those early PC gaming days were about borderline geniuses writing terrifying graphics engines.

Jolly good interview with Tim Sweeney, with lots on ZZT (hurrah!), and, I think most interestingly lots of on building games around editors and tools - from ZZT through Unreal to the present day. I like his acknowledgments of his shortcomings as a progammer - but perhaps also his shrewdness as a manager.
