Re: Elite presentation by David Braben

Last year the Game Developers Conference had some presentations by people responsible for classic games.

David Braben did one on Elite - which, given the discussion about an RPi version of the game here, I thought some of you might be interested in.

<t>IBM's Visual Age products (for Smalltalk and Java) used to work in this way.<br/> <br/> The GUI designer also let you draw lines to define the links between UI controls and would generate the code to support them. The problem was the generated code looked pretty horrible. If you just used default...
