I seem to be one of the odd ones out of the bunch of ME fans, but I was rather displeased that they completely eliminated the Mako exploration of planets routine in Mass Effect 2. Sure, it got to be a tad boring and drawn out at times, but the whole idea of exploring unknown and creepy planetary surfaces was enjoyable and sold the idea of a large and hostile galaxy. I hope they do something similar on ME3, albeit keep the boring / monotonous element out of it.
