Mass Effect is really one of a kind. The first game is the most epic Space Opera that I have ever played/watched. It puts Star Wars and others to shame. They retconned shit in the 2nd and 3rd games so in my opinion the first one remains the best story-wise. But honestly, all three are great.

I am very sad that no other studios tried to do anything even remotely comparable. The closest I can think of is Starfield, which wasn’t very good.
