Sam2014: I have very slow internet and Internet Explorer 11.
The site will not even load, much less than log in.
Yeah, GOG has been coding against IE for quite some time now, elements of big sale pages, the profiles, chat broken for a while (though eventually they fixed that), now they just "graduated" to have that coding style apply to the whole site, except the areas as yet left untouched like forum, library or wishlist. Nothing to do with connection speed, it still won't load regardless of how fast your connection would be. Which isn't to say it's not slow and bandwidth-hungry (and also CPU-intensive) when it does work, of course, because it is.
Sam2014: I think most of your customers are older,
not mostly kids.
Not so sure. Probably not a case of age in itself though, but of maturity, also including attention span, impulse control, knowing what you want, supporting values. In that sense, the GOG userbase sure used to be some levels above the average, but they've been catering to the same mindless masses and seeking to "train" them to go even lower same as all the rest for years now, so maybe they've succeeded in creating a userbase made primarily of that.
