These Are A Few of My Favourite Things

- I missed the elevators from the original Mass Effect. So when they added them back in ME:A in the form of the Tempest's doors, it was a thoughtful nod to player nostalgia.

- It's great that we have to take off from a planet to interact with the Tempest's computers, instead of just walking in and using them. After all, they're ship computers - not planetary computers - they were designed to work in space. It's cool when science fiction writers think of this stuff.

- The research and crafting system is well thought out. Right from the beginning of the game, you gain access to all the cool stuff, and you can spend all your research points getting your favourite weapon from ME's recipe. Then, after you've spent your points, you get to go in and see all the cool materials you'll need to build it that you won't have access to until late-game. It gives us a way to spend currency on the anticipation of something that we can't actually use.

- They made it so that black holes are clearly visible from across a galaxy. Science!
