Hi, Robert,
Here's the
Catalogue. Right at the top you can use the drop down menu to Browse by Title, which is definitely an easier way to find games! Just click on a link to find info on the game and buy, though you'll have to create an account
first...I think. It's been a while.
Here's the
Forum page. You'll see forums for all the games or you can click on the General Discussion Forum link right at the top to ask a question of the entire community.
It can be a little daunting getting around but it's not bad once you get used to it.
GOG has a support link at the top of the home page and most of the others if you have a problem you can't solve without their help but you have to remember they're probably in a very different time zone and sometimes their answers take a while.
HTH,
Gil.
