I completed it a couple of days ago and I've spent the weekend blasting through it and collecting Achievements.
When I first played it, it was a good looking game with respective gameplay, a story that was pretty tough to care about, and some boring live action cutscenes that put me to sleep every time. I loathed the "Canon fodder" faceless, nameless enemies.
For some reason, this second play through is much more engaging. The firefights are more fun. The story is engaging, and the graphics are somehow more impressive. I find myself pausing and taking screenshots of various facial expressions. The whole thing just seems better, now.
It's not perfect. I hate how enemies all sense when I'm about to attack. There's waaaaaaaay too much reading of open emails. Some of the characters are generic and forgettable. Still at 8/10 for me. What say you?
