MGS4 wasn't that great of a game, compared to some of the other ones.

MGS4 was good but It is not great. It simply is not the best title in the series, it just did not have the same feeling as The Twin Snakes and MGS3 have.

I personally love MGS4.

I've kept up with the series since the first Solid game, and the last boss fight in MGS4 was seriously the most epic thing ever. That and controlling Rex, way to fanservice Kojima.
