For every mission, I get a LONG list of achievements: Good.
These achievements contain all the ways I can complete the mission: Good

This is how it was in Absolution... So far so good. But:
The new game contains such achievements as : Throw an egg on a graffity 4 times, and get an easter egg. Well, here's the problem.

You can set to either show, what the achievements mean, or not. So, if you don't see it, you have no idea how well you understand the mission, since you don't know what achievements are bullshit. And if you see what do they mean.... SPOILERS!!!!

There is no way to enjoy the game's exploration, and completionism at the same time.

That's so fucking stupid.
