Try it and you just might like Turok.
Graphics- Nice looking, maybe not the best in the world but nothing to gripe about really.
Guns- The guns are top notch in Turok. Each one is unique and really quite fun to use. With all the dual wielding, alt fires, special knife kills, stealth, and sniping strategies you will really never play the same game twice. If nothing else you have to give the game A+ in gun creativity and uses. Although there one issue with them; There is a bit of a learning curve since they use a press shift + mouse button combo system to use the alt fires.
Story- It's fairly simple for the most part. Kill the bad guys, survive the dinosaurs, stop the baddest bad guy. Not so deep or anything, but the acting is gritty and top notch with great actors such as Ron Perlman in the game.
Gameplay- Some say it's too "by the numbers", but I found it too be much deeper especially when you challenge yourself on difficulty levels, use a variety of weapons and strategies, and go for some of the achievements available. I've completed Turok 4 times, completing all the singleplayer achievements, and had a blast the whole time.
The Bad- Multiplayer is a joke with no server browser and nobody on. And the loading times are very long, so bring a TV with you to watch during the breaks ;) . Turok requires a lot of hard drive space too, more than any other game.
If you can look past the flaws, this is a very fun game. And if you like sci-fi shooters like Doom, Quake, or Half Life you will probably enjoy Turok as well.
