Dev Game Club is a conversation between two working game developers who have been there. Each week, hosts Brett Douville and Tim Longo pick a classic video game from the past-often a title that shaped design thinking or introduced a new technical standard-and break it down from their professional perspective. Their discussions go beyond nostalgia, examining how these older titles functioned, why certain creative decisions were made, and what lasting impact they left on the industry. You’ll hear specific analysis of game mechanics, narrative structure, and technical achievements, all filtered through decades of hands-on development experience. The goal isn’t just to reminisce but to extract tangible lessons that are still relevant for creators and deeply interesting for passionate players today. They invite you to play the game in question alongside them, then settle in for a detailed, insider’s post-mortem. This podcast offers a unique blend of critical appreciation and practical insight, treating video game history as a living textbook. It’s for anyone who loves games and wants to understand the craft behind them on a deeper level. New episodes release regularly, diving into a different influential game from the archives.
