You can get the games here: https://items.gog.com/freedomtobuy/index.html

Side note GOG games are DRM Free meaning you own all the games you get from them. This is different from steam as Steam only lets you play games if it can verify you purchased them. Meaning if steam ever goes down or take down certain games you might not be able to play them even if you bought them fair and square. This is another reason I like GOG. They are very dedicated to letting gamers preserve their games.
