So i took a look over at the Steam threads.

Wouldn't bother me, 90% of the time I don't even notice the achievements pop up, especially on Steam, it helps that they are rather small and do not have any audio. Plus, I still maintain my opinion that if achievements are "game-breaking" for someone, to me it only means that the person is waiting for it to pop up, like paying attention to the achievements more than the game itself.

There's plenty of ways they could implement this anyway, such as having the achievements be unlocked at the complete end of the game rather than while playing it, or have them pop up when returning to the Main menu after a gaming session, etc.

But in the end, whether it has them or not won't change in a single way how I will play the game, especially one such as Amnesia.
