So I had decided against this game for a while, based on the number of technical issues people had been reporting (and a real lack of time on my hands to play through an epic Bioware game). After months of hesitation, though, I finally went out and bought it, and it's great!
I expected the worst on the technical side of things, and I haven't found them to be bad at all. The little frame rate dips, texture pop and occasional screen tear are really trivial compared to the game's scope - this game is BIG, and DEEP. A little framerate dip is nothing when I'm zipping around a galaxy. And the graphics and cinematography are incredible, which makes the story a lot more engaging.
I love the branching dialogue trees - instead of dreading long conversations, I actually look forward to them. I feel like I'm given the choice of more realistic answers, rather than the standard "good answer, bad answer, neutral answer" options that you're usually given.
The combat isn't as solid as a dedicated shooter like Gears, but it does the job, and I prefer it to anything turn-based, which is wholly unrealistic. It'd be nice of my teammates pulled some more weight, though.
