I really wish 4A would allow us to save whenever we want. Manual saves and checkpoints can co-exist in harmony just fine. People who prefer checkpoints only can choose to not press the quick save button or visit the save menu, it is that easy really. And as far as I am concerned a steady progress is far more immersive than playing the same difficult sections several times, listening to the same conversations until you can repeat them word by word correctly. While the level designers overall did a competent job at placing the checkpoints I still had a lot of long repeats, namely during the stealth sections, me saying "Are you fucking kidding me? I go all the way back here?" was not uncommon.
And there are some inherent flaws in the implementation of the save system. Suppose that you are in Dead City 1 and want to explore the final area. Seeing as this is your first runthrough you walk straight into an endlevel trigger without knowing it was there. No biggie. Now you just go to the menu to load the last checkpoint from the previous level an- oh wait, it is gone. You have to replay Dead City 1 from the beginning if you want to fully explore that area. This limitation also translated to me thinking that checkpoints were not stored, because when I started the game I instinctively went to the load menu which only lists the auto-saves. Then I found that Continue main menu element. Maybe this would have been less of an issue for me if they hadn't made the main menu so fucking graphical and annoying, menus should always be a list of text items, like every other menu screen in the game.
Fuck the person responsible for the stuck-to-a-turret / stuck-to-a-vehicle sections of the game. Does anyone honestly enjoy these? I ended up godmode-ing the journey through that target practice bit where there were like a dozen enemies shooting at me from left and right as the vehicle slowly moved. Then I learned that scout at the start is actually killable, because I got the impression that he was invulnerable to my weapons. And is it just me or do those enemies only attack Artyom and not the friend next to him on the platform? Considering he is wearing armour and I a stealth suit distributing the damage REALLY would have helped.
And I have to question the filter mechanic in this game. May I ask why the last new filters you can buy are only in Market, and why you can not pick new ones up until you are below something like 15 minutes? That is fucking retarded. You can carry hundreds or even thousands of ammo rounds but not an hour worth of filters? If you haven't played the game before how are you supposed to know you should fully stock up on them in Market so that you don't risk destroying the game for you later? I would have no problems with the gas mask mechanic in this game if it was well implemented, but as it is it is seriously flawed.
That wall of text being said, as you can guess I don't want to see these things appear in Metro: Last Light. While Metro 2033 is an excellent game there is a vast room for improvement and I hope 4A will grab the chance and learn from their mistakes, and considering that they will shoot me in the balls once again with the same sadistic save system as before I'm not keeping my hopes up.
