keeveek: Once again. No reason to land on them (if there are no casinos) with live crew when you can send a probe.
Fenixp: I do agree with that as far as resource points marking is concerned, but when you detect something actually interesting and know that the planet's conditions are fine for a crew to land, why not send a small team? I mean really, they will most likely inspect the locations much more troughoutly than a drone, since they'll know what to look for and how to react - well unless the drone's controlled by an AI. Which it can't, obviously.
You send your live crew to toxic environment without suits capable to stay outside mako for longer than just a few seconds in ME1 too ;P
Also, the Mako controls were horrible. Making turns was clunky and fights? Well, most of the time you were firing from a distance driving back and forth to avoid being hit, and that's all.
Booo-riiing.
At least planet scanning lasts a few seconds...
And if you found an anomaly, you were landing anyway, so...
