Without a doubt one of the best games I've played in the last five years, and the first game I've ever finished more than once (Currently on my third playthrough, first as operative (Starting XP in stealth and pistols), second as recruit (No starting XP), and now as a veteran (A LOT of starting XP)).
This is a game that many reviewers will mention a few years down the line as one of the most important games of this gen. Sure, it gets some stuff wrong, especially when compared to other shooters, but the stuff it gets right more than makes up for it. Funny thing is, most of the stuff it gets wrong as a shooter, actually make sense for an RPG. If you're not experienced with a certain weapon, it makes sense that you will have to steady your aim a little longer to hit your target.
I'm playing through Mass Effect 2 right now, and in addition to encountering WAY more bugs and stalls than I've encountered in my hours and hours with Alpha Protocol, I constantly find myself thinking "Why isn't this more like Alpha Protocol?".
Awesome game, shame we won't get a sequel.
