Exodus is an upcoming game from former BioWare devs, and they've answered some pressing questions in a recent Q&A like will your choices affect the outcome of the game like they do in Mass Effect or Dragon Age?
One question asks, "Will all of the missions involve choices that impact loved ones over time due to time dilation?" Exodus is a space game, and if you paid attention in your physics class or while watching Interstellar (don't worry if you didn't, I did), then you'll know that the faster something moves, the less time it experiences.
The devs previously explained the mechanic, saying, "When Travelers go on Exodus, they will age much slower because of the effects of Time Dilation.
Anyone they leave behind, including friends, family, and other companions, will age much more rapidly than those who are on the journey." As a direct answer to the above question, however, co-founder of developer Archetype, Chad Robertson, says, "All your missions are gonna include choices that have impact, but not all of them are going to include time dilation," so you don't need to worry about everyone around you growing old constantly.
Well, unless you're traveling close to the speed of light on an exodus, that is. Robertson continues, "There's a big story in Exodus and you're going to be making choices throughout the entire game, of course.
