Why does this game get harder as I go with this difficulty curve of these quest even on very easy difficulty? This game will be my final game I'll buy from you until you improve the game and get rid of difficulty curve.

Isn't that how a game is supposed to be? As you progress through the game, you should be getting better weapons, armor, power armor, better perks, and more general skill with the game. It SHOULD get harder as you progress, regardless of the difficulty. You're leveling up, and so are the enemies. I think you are very much in the minority with this request.

Are you sure you're not simply venturing into areas that are best left until you're at a higher level? If you see enemies with skulls next to their names, it's an indication that they are at a much higher level than you are and it may be wise to leave the area alone for a while until you've leveled up a bit.

So how do quest lines equate to the difficulty curve? Are you talking about the main quest and how things get harder as you progress through the game? If so, what games have you played that don't do this?

I don't understand how bethesda could have dumbed this down more for you. This game is laughably easy on survival and the perk system is so generic any choice is right.

I don't think the questlines are BAD per sé, but there are too many obvious options left off the table (suing for peace, for example).

Man, have ever played any games before?? lol

Both anolog and digital games get harder as you progress.

Well, it's clearly not a problem a lot of people are having.

What sort of character are you playing? Some builds are a lot more efficient than others. Do you have a decent set of combat perks? Where are you in the MQ? What level is your character? Do you use VATS?

It can be difficult, even on very easy. A lot depends on build and playstyle.
