I have visions of driving a Mako around for hours in Mass Effect on almost barren planets with a few collectables.
Yup imagine kind of similar, or scanning the local environment. Can see in the trailer, on the moon where they show a outpost being built, literally shows the collectables on that particular planet, in this case resources and 100% once you got them all. Can imagine that being similar in many cases elsewhere.
For me, still very excited by this game, just think people may be disappointed if they are expecting anything special on the 925+ or so planets outside the core ones IMO.
