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.

Useful reference material! (And: he's totally right about the Nikka).

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.
