I wouldn't necessarily call Mass Effect hard SF. The concepts it toys around with are based on real-life theories of dark matter and dark energy, but with many liberties taken. What Mass Effect does, though, is present a set series of rules that do not change. Thus, the technology in their universe is internally consistent, if not necessarily realistic. And that's fine with me. The dev team created a world that at least sounds plausible, even if it's really far-fetched. And I like you appreciated the codex entries. Beyond science, they delved into the history, cultures, and figures of their universe. What I loved about this game and others is the depth of the universe. I want a world I can be lost in, and one as well thought out as ME's was just that. So I appreciate the background info in games, and I will never criticize ME for being wordy.
