Until Enslaved, I hadn't experienced such a WOW! factor over a game's graphics since I played Uncharted 2 a year ago. The amazing art direction and visuals provide a fitting backdrop to one of the more engaging and fun to play adventure stories I've played since, well, Uncharted 2. This is supported by an excellent soundtrack and voice acting by the three leads (everyone focuses on Monkey and Trip, but a third character--I won't spoil it--really steals the show). This game isn't quite as polished on the technical side as it could be, with some minor controller issues and audio glitches and screen tearing (I never really understood what screen tearing was until I played this game), but they didn't create enough frustration for me to spoil the experience. In fact, after I played the first few chapters, my only thought was, "This is why I started playing video games in the first place."
For those who thought the combat/gameplay seemed boring and repetitive in the demo, there is definitely a lot more variety as you get into this game. And on the harder difficulties, like any good game, a lot more strategy is required. I for one appreciated that my immersion in the game's story was not hindered by needing to memorize endless lists of long combo chain button presses. There was just enough variety in the upgrades to keep the combat simple yet satisfying. And while the platforming was rather scripted, as has been pointed out, again, I appreciated that my immersion in the story wasn't constantly broken up by a lot of cheap deaths.
I expect to see Enslaved's name come up in a number of end-of-year game award categories including best writing, story, acting, sound, soundtrack, graphics, art direction, and action game.
