Haven't been following much regarding the Nomad if there's been information previously shared by them, but despite everything looking really great and all, I'm a little uneasy about the terrain they're showing off with the Nomad in this video.
Still haven't played ME3 yet, as I'm currently playing through the series for my first time and on ME2, but I hated the Mako in ME1 not because of the controls, but because it was basically a massive empty environment with like 3 waypoints randomly thrown about in opposite corners of the map. That's not fun to explore, and that's literally what the environment they showed off in this video looks like.
Like I said, I haven't been following the game all that well, so hopefully all signs point to this just being a method of theirs not to spoil the actual contents of the environment, and focus more specifically on the Nomad's functions.
Edit: Wait, the Nomad has no weapons, and you have to manually drive around in an empty environment dropping those drones off? They created and refined that feature to be one of the many random mini-games in ME2. Why's it now becoming this game's version of running around gathering plants?
