The stickerbook is tangible to me. I like veteran and hard modes for the challenge and the rewards, but don't count titles and achievements as such. In one case achievements actively interfere with my enjoyment of the content. I'm talking about BGs. The scoresheet that's shoved in your face at the end remains unfathomable to me. Achievements such as "near death kill" are nonsense. Congratulations, you almost died? That's not something you aim for.
