User blog comment:TheUnknown285/Things You Do and Don’t Want from ME4/@comment-4950455-20140613002615

As for my own thoughts, in addition to endorsing pretty much everything in the original post one thing that I'd really like to see is the return of a degree of scientific rigor to the series. It was very distinctive in the original ME to see some of the things that were at least acknowledged, and I feel like ME3 in particular moved away from that in favor of a more Hollywood style. Since it's been strongly implied that ME"4" will be smaller-scale than the all-out armageddon of the Reaper War, I'd like to see a return to slightly more down-to-earth tech and whatnot.
