I bought the first fallout and the second here a few months ago (they were free then) and I try to put it on steam and verify it so it shows that I played it for x amount of hours and I would like it to show this.

So my question is, could I have the keys so that I can show on steam?

.

The games have no keys. The way to play them on steam is to open Steam, click on the "Games" menu and choose "Add Non-Steam Game to My Library." It will give you a list of installed programs and you'll check Fallout and Fallout 2. Fallout will work out of the box. You will need to right click on Fallout 2 in steam after you add it and go into properties. To "Target" you will need to add a space and GOGFALLOUT2 at the end or it won't run.
