Just what I expected after playing Metal Gear Solid 3.
The storyline of this game is great, but there are not original bosses, they are all the same bosses from Metal Gear Solid, in others bodies and lives, but it's a cool story. Big Boss died from Snake Fox-Die and Snake is dying from his own Fox-Die, that's doubly sad :(.
The graphics are pretty good, and they're one of the things that make this game pretty good, but the only thing I think they could improve, is the first person-view, because it's good but still not perfect.
The sound effects are pretty good too and realistic, and they are in any game, what could make it good or bad.
Metal Gear Solid 4 have many weapons, that's my favorite part of any shooting game, it's fun change the weapons, shoot with then even if you shoot the air, because you want to test all of then (trust me, it's my personal experience).
This game is fun, have good graphics, good sound effects, so in my opinion there's almost nothing lacking to Metal Gear Solid 4, just little details that I don't like to comment because I like this game and I rated it 10.
Metal Gear Solid 4 is great game to all the Metal Gear series fans, if you are one, buy this game and you will really like it, I guarantee
