I love to procrastinate on the main quest, and apparently this will be worth it in Mass Effect: Andromeda. I caught a GameInformer article summarizing a recent BioWare interview with PC Gamer. Here's the link: gameinformer.com/b/news/archive/2017/02/12/report_3a00_-mass-effect-andromeda-to-feature-meaningful-side-quests-similar-to-the-witcher.aspx?utm_content=buffer21574&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer. (The original article by PC Gamer is linked in this article.)
Instead of killing some random mercs and cultists, we'll hopefully be getting a wealth of content that means more than XP and loot.
