The original Dues Ex set a standard for FPS with choice.
*Between improving my digital art skills or playing video games, I, sadly, had to conclude I couldn't (personally) do both, so, I picked digital art because it was more important (to me). It's worth every dollar, buy it if you can! To keep it short, there's roleplaying in the game, and, yes, you can spend hours just absorbing game lore or poking around other people's apartments, offices, etc. For the sake of brevity, I'll forebear gushing about the roleplaying facet of the game. If corpses and gore aren't your thing, there's always a more subtle, even cerebral approach to every situation. While the levels are ghostable, as I've seen via more seasoned players, there's an embarrassment of options from carpeting the floor with bullets to surgically stalking and stunning/killing NPC's. 'Deeper not wider' is 'Human Revolution's modus operandi and it never DARES to deviated from it.
Having never played any of this series legendary precursors, I can say, without reservation, this game, having never finished it (for the sake of time management*) was the most engrossing and exhilarating experience I've ever had with a video game.
