Turok is arguabally worth a rent -- only if you don't need the money.
Now onto the Dinosaur killing.
Gameplay...heh. It takes a lot of shots to kill the humans, and it takes like 3 to kill a dinosaur. Not sure how that one worked out, but congratulations to the developer on that one.
The gameplay is fun, and unique to the extent that you get to kill dinosaurs. Other than that the game doesn't pull you in with suspense or blow you away with intensity... it's rather bland. The exact word my friend and I came up with after about an hour or two of gameplay was "bland", and I stick with it all the way through the game. Out of all the PS3 shooters...this one is near the bottom. Not as bad as Conflict: Denied Op's, but still.
The graphics aren't bad by any means, but they aren't groundbreaking either. I'd say they're par for the course overall -- with the exception of the knife animations. The knife kills are pretty cool looking (Like Assassin's Creed kill camera, but not as good of graphics) and make you feel accomplished when you get one. 8/10 on graphics sounds pretty fair to me, if not a little too fair.
The sound is good in the game -- once again not groundbreaking. The voice acting is good, the dinosaurs sound excellent and so do the enemy squad commands. The gunfire could be better, IMO, but still not bad. 7/10 on sound.
Following paragraph contains minor spoilers.
The story telling, in my opinion, is pathetic. I know FPS's aren't known for their intricate story telling, but this one takes the "leaves more to be desired" cake. The beginning cutscenes introduce you to the story (albeit in a fairly straightforward "forget the details" fashion) and leaves you wondering what exactly is going on as you begin playing. The only thing I really got for sure is that as Turok you're after a fugitive and ***spoilers*** your ship was shot down by him on this planet you've crashed on. The story to me is 5/10 -- even CoD4 embraced you into the characters with limited story telling -- Turok didn't even do this.
I liked the controls quite a bit on this one. You can dual wield weapons (always cool) and shooting / reloading / crouching and standing is easy and you can pick the controls up within minutes -- especially if you've played other FPS's. Overall I'd give the controls a 9/10, the major bad thing about them being the knife mechanics. Using the knife on the fly is usually uneffective at best -- partially because the button-animation relationship is off -- but that's just me.
Multiplayer is fun -- don't get overly excited about it, not as good as CoD4, Resistance, R6:V, etc... seems like everything about this game points to
"not done as well as...".
Overall I'd have to say that this game is a 7.5/10 at best. It just doesn't make me want to keep playing... not even the wicked compound bow or knife kills. They just don't make up for the lack of intensity or solid gameplay with anything to keep you interested. 7.5/10 = final verdict.
