It's alot of hype and I want to know, is it really the best game on PS3? Will it be like a movie, but I just have to press buttons? Does it have a good story? Will I be let down? Is the online like COD, but third person? I like games that have deep, very interesting stories, like Assassin's Creed or Fallout 3. Will I really feel for the characters or will it be like Naughty Bear, where I really didn't care about the teddy bear that I played as? I traded it with a friend and got AC 1. So, what I am saying is, is it worth almost $80 for them with all of the DLC?
I think regards video games 'best' is a tricky word because obviously it's always down to opinions. It's very cinematic, absolutely beautiful looking infact. It's a linear game, but each area you go through is a decent size. I loved the story - so much so that in parts I was a little distracted by it my shooting was off LOL There is a lot of gunplay, a lot of exploring and a few puzzles. You absolutely will feel for the characters - possibly moreso than any other game.
The online, I haven't played COD so I can't help you with that comparison. It's great fun though, and there is a nice variety of gametypes so I think there is something to suit everyone pretty much.
