The above helped so much, omg. Now if only there were an easier way to navigate those pesky planets omg. I ended up doing all my Assignments one after the other, because I suddenly realised that I'd progressed the story so far that I wouldn't have a chance to do them later on

I'm sure I missed out on a lot of side quests because of this. Oh well.

I would never have had the patience to complete all those "COLLECT THIS AND THAT" quests anyway, so muh. Though I were pretty close to finishing some of them. .... and I scanned 19 out of 21 keepers. WHERE WERE THE LAST TWO? FFFFF

One thing really bugged me about travelling the universe, though... not being able to look at your journal while in the Galaxy Map!

and the fact that doing all the assignments in one bulk got kind of tedious. All the planets ended up looking the same :/
Anyway,
I completed the game!

Which is further proof of how awesome it is. It usually takes me ages to complete a game, and end bosses are usually way too daunting for me to kill off T_T. It took me about 30 hours to complete this, and I thoroughly enjoyed all of it. I did play on casual, which I thought would get rather boring... some fights were, but most were just fun. Fun is better than boring or overly challenging, so I stuck with that. Might try a normal playthrough some time in the future~
My character's personality ended up being a bit wishy-washy, but I ended up with plenty more renegade points than paragon ones

I romanced Liara, ditched Ashley, and left Kaidan heartbroken

I also got the "Rich" achievement, because I never found anything to spend my credits on

I think I've got the Casual mode to blame/thank for that one.
