I'd disagree with this, but the choice is yours.
I say play the first and once you get through the Citadel and get your own ship you'll fall in love with the game.
Those first few hours can be a struggle
the combat is better in 2, but the first is a far better game.
I completely agree with this, the first couple of hours are a bit meh but after that it's ace.
I played this game on the very first day it came out and I remember near the end it took me 3 weeks to get back into the game and complete it as it bored me.
I've now just finished replaying it and this time I didn't get bored at all, it's such an amazing story and I've no idea why I got bored the first time

Oh and back to the main point, definitely play the first as the story is great and the ending is awesome. It also helps you understand the 2nd part.
