I played and beat MGS4 in the first few days after it came out. Put it away and didn't really think about it until now. I was honestly kind of disappointed by it over all, in hindsight I realize that was just because of my over inflated expectations. Yesterday I put the game in again. I am now about half way in and I have to say, Its gotten better. MGS4 is a masterpiece. I would go as far as to say that its even better than MGS3 which is generally regarded to be the best in the series. This is how I feel anyway. I am sure you all have your own thoughts about it.
I am also even more excited to play the MGS HD Collection. Especially for Peace Walker which I barely played because handhelds are just not my thing.
