I would just like to comment on these scanning tips, particularly Tip 4. I have played through the game 3 times now, and am on my 4th playthrough, and I don't find this tip to be entirely truthful, and even when it does show some actual merit, it is still all but useless.
Most of the Rich planets I've come across seem to be more or less random in their visual appearance. For the sake of argument, let us say, as Tip 4 implies, that I find strong peaks at a certain - for lack of a better term - visual locus. If I try to find more of such areas such that I may find rich resource deposits, I save myself no time than if I had simply done a complete grid scan. This is because not every identical visual locus is a resource find, and they are, more or less, randomly distributed, even on the "Garden Worlds" that are comprised of vast and world-spanning archipelagos, evidently. So, while the resource caches might be tied to visually similar loci, these loci are, thus far, demonstrably randomly distributed.
Also, I would like to point out that resources only "tending" to be found in areas that are visually similar is also a far cry from the truth. I've scanned worlds where this does hold true, somewhat, but on those same worlds (let's use ME2's more Terran-looking world map), I've found a single type of resource both in the middle of a landmass, and in the deep ocean. Of course, I am only guessing that the brownish-green is land, and the dark blue is deep ocean, still, these two are not visually similar. Tip 4 becomes even harder to employ on the less Terran-looking worlds where they might be just bands, or even have a frothy looking appearance.
This is not to say that I dislike the new resource gathering system. Sure, it could use a few improvements and rationalization, of course, but I find it leaps and bounds better than bouncing around in that cursed Mako. I just feel that Tip 4 is misleading and mostly useless when establishing a search paradigm. Other than that, awesome game. I really enjoy it.
One final note: being that the large part of the game-player base is male (not diminishing the importance of female game-players, but statistics are what they are), and being that the trait of color-blindness is more prevalent among men than it is among women, was it a good design choice to tie so much of the game to color-coding? Not saying that individual color-blinded individuals can't find ways to cope as I, myself, have in some regards. As the wise Joker once stated, "I'm just putting that out there."
