I definitely recommend the game. I got it on sale for $5, and after 1.5 hours I already feel I got enough fun for the money—and the game has only just begun. So, I think even the $17 for the game is well worth the price.
If you go in with right expectatoions into this game, you can definitely enjoy it. It delivers just what a $17 game should deliver; don't compare it to those that go for $40-$60.
There's no jumping in the game and you do occasionally bump into an invisible wall. There are some really grotesque looking people and I often want to find out what had happened to them, but alas, they just ignore you and there's no option to talk to them. Some characters stand in your way, [intentionally?] blocking your way. They're like furniture—no interaction with you at all—which feels lazy and lame on the part of developers.
What irks me the most is the UI. Every time you pick up loot or ransack a corpse, you get a popup message telling you what you found, and you gotta click "OK" to close it. This really should've been a brief message at the bottom instead. Quests, on the other hand, flash by so quickly, you don't get a chance to read what you have to do, so sometimes you gotta navigate into your quest journal to read them.
If you don't have your weapon out, SHIFT makes you sprint. If you do, SHIFT makes you roll. The problem is if you have to go up/down a cliff or ladder, you have to position yourself in front of it and click your mouse. The area where that click actually makes you climb is small, so you often miss it, and get your weapon out instead. There's no button to hide it, so then you just wait for it to be put away just so you could sprint again. Annoying.
Voice acting is mediocre in places, but the dialog is very well written.
The setting, story, and writing shine. I'm enjoying them so far. Combat system seems good too. It isn't a "click-until-they-die" stupidity, like in Skyrim. If you hit your enemy with the same thing repeatedly, they'll start blocking it. Dogs can't be damaged in the head, so you gotta try to get them from the back. There are stealth combat attacks, blinding sand throws, guns (though you don't aim to shoot them), and seems like a bunch of other "magic"-like attacks that you unlock later on. So I'm enjoying the combat.
A few other reviewers dissed the graphics, but they look fine to me. You get an occasional model that seems to bob a bit too much when idly chatting, but that's minor.
In summation, this isn't a $50 top-shelf title; don't go into this game expecting it to compare to such games. It's a $17 game and it's worth every penny. Voice acting and user interface are the the weak points, graphics are fine, and combat, setting, and writing are the strong points.
I definitely recommend this.
