Woas Trust me, the Mass Effect universe is a very different feel from Star Wars, not least because it makes more than a nod to hard science realities (like ships needing to bleed heat and being very easy to find against the relative cold of space, being unable to communicate when travelling FTL [aye, FTL is not hard SF but find me a setting without it!], etc).
I like both settings, but they're not similar beyond "stuff in space, with aliens".
