Game jams are marathon sessions where game makers put together a game in a short period of time, typically just one or two days. Naturally they're unpredictable -- as likely to conclude in quick interactive jokes as they are substantive games. Sometimes 48 hours of game development ends with Broforce. Other times it ends with Kitty Punch. Rather than invite all game makers to come together for a non-stop creative session, Antholojam founders Zoe Quinn and Alex Lifschitz invited creators to pitch ideas based around a theme and then gave them a month to complete their vision. Now there's Antholojam 1: A Golden Age of Sci-Fi Anthology, gathering together 15 beautiful and strange games resulting from the first of these curated jams.
