How does Mario know to jump when you press A? Do tiny video game gnomes watch your every controller movement and tell Mario what to do and when? Well, probably not, but if you’ve never made a video game before, then it might be difficult to know how they work. Not to fear, the Sacramento Developers Collective is hosting the sixth annual Progressive Game Jam, taking participants who’ve been dreaming of making their own video game through the entire game development process. By the way, let us know if there really are video game gnomes. 2533 R St. Suite 120, meetup.com/gamedeveloper.
