Guild Wars 2

Lots of people (me included) are completionists and just try to collect everything for the sake of collecting everything. Doesn't need to give me a huge buff to make me feel like I accomplished something.

I'm not saying that there aren't people who don't do that. I complete maps because I find it fun myself. My point is that there's a HUGE benefit to everyone if people do achievements, regardless of your purpose. There are people who did achievements just for the Blessing to help in runs. Everyone who got an achievement, regardless of reason, WAS rewarded. Titles here are just a status symbol, which is slightly a disappointment when they were beneficial in game as well as personally.
