pros:
- environment and level variety vastly improved from MGS2
- slight gameplay changes (ex. suppressor health) add a nice challenge
- volgin is easily the best villain so far
- story is anotha banger (shocker), while I do like MGS2's overall story a bit more, MGS3 definitely has better characters
- EVA and Naked Scenes were great

cons:
- lack of quick level restart is frustrating, especially when going for a zero alerts run
- camo optimizing became annoying rather quick
- no crouch walk :/
- when the game puts you in permanent 'caution' status and the enemies magically can sniff you out from a mile away (helloooooo ocelot unit)
- the fury boss fight
