very good game! please don't listen to the naysayers!
let me tell you this is a GREAT game, graphics aren't everything in life sometimes you need to take a step back and enjoy the damn ride.
GRAPHICS - yes the graphics range from good to very good, if you rename the executable to Bioshock.exe you can force AA in the nvidia control panel, make sure you disable also any nvidia Optmizations by setting High Quality in the panel it makes a world of a difference.
currently playing 1440x900 all high with 4x aa and 4x af (8x af will hurt performance unless you've got SLi or crossfire), so far performance is very good lowest fps 40fps and highest 60 (capped anyway), the dinosaurs and general animations look great, a few textures could've used a bit higher polygons but that's fine.
if you've ever played GEARS OF WAR well the graphics are quite similar or better.
SOUND - well the sound is an integral part of the experience, you're on an island (way too open) so you gotta pay attention with those little dinosaurs pests running around where you can't see them, 5.1 speakers and surround provided an good experience but this game shines on Headphones you've got my word on it, awesome voice acting (the characters are plain bad ass which is cool!), music is ok.
GAMEPLAY - all i can tell you is that while it shares the name and dinosaurs it's quite a different game from the original, but i gotta tell you also to stop comparing this to the old one, take the game for what it is and you'll enjoy it keep on comparing and you'll drop it real quick.
won't bore you with the story you must've read about it, but suffice to say you'll be fighting enemies such as soldiers combines and dinosaurs including a T-Rex! oh yeah, weapons feel great, the characters are likeable in the context their in, the story won't win any award but it isn't half bad either....bad guy end up on an island with dinosaurs and gotta fight....good mindless fun.
CONCLUSION :
sure the game could've been better by improving a few things but then it could've been worse, honestly this is a great game and if you can forgive a few niggles you'll love it as much as i do, it's FarCry vs Jurassic Park really.
