Shmacky-McNuts: He person said they were joking, after I wrote this.
HiPhish: I know, but humour works best when there is truth in it. I'm sure there are enough people who will be willing to do mundane things just to get some useless shiny sticker for it. I'm not saying they will buy a game specifically for the achievements, but there are enough people who will be willing to wast their time taking turns shooting each other in the head just to unlock a golden AK. Not even joking.
https://www.youtube.com/watch?v=DAn-BlR9PVk Internet, forums, youtube, and communities in general give us sometimes a twisted impression about users.
Meanwhile you have "buzzy" users that of course do that, and many viewers checking what that kind of users do... you can also have a big number of customers, probably mature, like GOG has, that they do not post so usually in the internet, that they do not make so much noise, that they do not pursue achievements, stickers or these kind of things, but still spend a lot of money on games.
For Instance, I do not follow many Youtubers, and the ones I follow I check them very few times, I do not post much on Twitter on my personal account, or in Facebook, a different thing is at my Job, as I actually worked in Marketing and as a Social Media Manager, but in my personal part of the day I have no time to enter every single forum of every single thing I like and consume, to complain or praise products every single minute, and I am not a friend of Tweeting the whole day, it consumes much time of my job and personal life, and when I have free time, if it is related to gaming, I love to simply PLAY.
For instance, my last month with the insomnia thing, (My wallet hate you GOG guys) I spent around 100 dollars, also I been a very active Battlefield player, with more than 4000 hours of Gameplay in several years and consume almost any of the DLCs they launched, but I barely posted anything on the Battlefield forums, and like me, I bet, many others. Of course companies know Youtube is trendy, or Twitter, and they use these plataforms to get feedback from the costumers, but just focus on what makes buzz in the internet is making close your eyes to a big piece of the cake out there, there is people that prefer to use their time actually playing games, instead of making/seeing videos, or talking about in the internet, usually older gamers with less time to populate forums or gaming social platforms. GOG got this piece of the cake doing something different, of course you need to pay attention to the BIG audience, and they are trying constantly new things, evolving is good. But if you do what others do, you need to compete with who is doing it better than you in that terrain, and not even EA or Blizzard can compete with STEAM.
I have near 500 games on STEAM, and I NEVER used any social feature on the Platform.
Just my two cents.
