MGS3 in my opinion took the series in an excellent direction. The use of the camoflauge with the environment was a welcome edition to the series and definitely a step in a good direction. However 2 things must need changing in my opinion to keep this series great: 1) the CGC system definitely needs retooling in a major way. Personally the way it is now is severly outdated and needs to be fixed. 2) stop being so wordy and so many cutscenes. Back story is great along with dialogue but lets please reduce it the amount this game contained was ridiculous.
Overall the game was outstanding, the switch to more of an outdoor setting was refreshing if not maddening at some points. The cure and food system definitely a great plus in adding a little realism.
Overall keep up the outstanding work and my hopes on a great MGS4.
