We mainly use Perforce as our source control. So I’m most familiar with using that, but I’ve made some smaller games and downloaded a couple of things using GitHub before.
When it comes to planning and time tracking, I generally use Jira and Toggl for those. We have also used Trello before.
This project was to create a game in Unreal with a limited amount of time. Our group decided to create a strategy game where the goal was to rob a caravan of their items, you would do this by defeating the opponents using the strategic placement of your own characters, and then using what they can do to eliminate them one by one.
