Another thing that helps is if you are really into that sort of sci-fi...me, I can't wait (literally, because I'll be dead by the time it happens) till we discover Lightspeed travel and (if it is possible) FTL travel.
So the story was particularly engaging for me because it was like exploring a possible future.
My advice if you get dragged down, ...stick to the main story, main plot. Avoid subplots, hard to do if you are a completionist. But once you find yourself getting into the story (which gets better and better towards the end) you'll find the subplots /sidemissions will be more interesting to do.
Also, CHEAT and add one of the skills you get for doing a certain skill a bunch of times... personally I love THROW even though it is not the most bang-for-buck skill...but lots of fun and makes you feel like a jedi
I believe it was Einstein that said it is possible to travel slower or faster, but not at the same speed as light....I'll have to double check on that.
As far as skills go, max level lift was by FAR the most overpowered thing ever. You could literally just float an entire room of enemies and blast them out of the sky one by one. It was followed closely by the one that placed a rift in the air that sucked everything within range to it.
