Well, it's satisfying to S-rank a game. But I'm not really into that kinda thing. I like achievements in WoW that actually reward ingame stuff instead of just points.

I used to but you get over it eventually. My gamerscore used to be ridiculous, and at that point I realised I had a bigger gamerscore than anyone I knew but... what was the point? So I've stopped getting achievements just for achievements. That doesn't make them bad though. I still pursue them in games I am having fun with because I am a completionist.

I still really like going after achievements, it's just adds to the whole experience. And that sound...

I'm not too bothered about achievements, but that sound, it's awesome! 

If an achievement is both interesting and fun then yeah- I might aim to get it. I'm not the type to S rank games though.
