Yeah, I'm loving it.
To expand on what Slug said about the difficulty, I'm in agreement. It's done a pretty good job of proving challenging on Normal whilst not being too difficult. I find a lot of games nowadays are too easy on Normal, but too hard on hard.
There's only been one level so far where I've felt like smashing my controller.
Also, can you upgrade the Normandy at all as you did in ME2? I've scanned stuff, but not to any great depth.
