Welcome to Dev Game Club, where this week we conclude our series on Populous with a special guest interview with Glenn Corpes, the original programmer who came up with a little generator for height maps that ended up launching a whole genre; we'll talk about that and tons of other topics. Dev Game Club looks at classic video games and plays through them over several episodes, providing commentary.

Podcast breakdown: 0:45 Interview 1:18:41 Break 1:19:02 Next time

Issues covered: how Glenn got in, seeing a computer for the first time, being a computer operator, getting a job for your woodgrain, getting hired as an artist, porting a game without the code, winging it on things like collision detection, being unable to port something and casting about for something else, writing a level generator to avoid writing an editor, having to add the ability to raise and lower land, having the whole world with a pixel per cell, the game on top being all Peter's, working backwards from mouse coordinates, having the original disk, the potential for the landscape to rise up over the interface elements, updating the map every frame, limiting the use of the blitter, size of Bullfrog at the time, the musician/salesman, understanding the "metal-bashing aspect" or not, three man weeks of graphics, blocks vs sprites, one thing per square and no more than 256 total, managing character state, no pathfinding, map steps: the opposite of pheromones, buildings based on the flat space around, people as groups of people, the interaction of weapons multipliers and population, getting an explanation of what all the bars mean, the most significant digits, the strategy for managing population, the strategy for clearing land, a clarifying button on the SNES, near-launch title, sales and the UK Chart, multiplayer only until shortly before ship, communicating through a networked file, writing the game in 7 months, watching two AIs play each other, the ways in which AI difficulty is managed, reimplementing all the gameplay in two weeks, faking out the AI because it will always attack your oldest building, AI speed, responding to flood, the manna rules, going into a manna debt and paying it off, making inroads for the knights, stuck messages, adding a campaign two weeks from the end, having an accountant QA the game, the most difficult level of the game: Biloord, how to beat "Biloord: The Hardest Level in Populous," slowing the game vs arcade-ing it up, faking out a sphere, making the cube without the stickers, flat land as currency, synergy and serendipity, revolutionary gameplay from an unexpected place, last minute additions, fights on Populous: The Beginning, heretical choices in game development.
