Search Tip

You can search without logging in, but here are three great features you're missing:

1. Pick up to 6 Steam friends to see what Co-op/Multiplayer games you all have in common (via Friends search tab)

2. Filter games you own out of the search results, if you're looking for something to buy. (set "Games you own" to No)

3. Find something fun to play that you already own, search by genre, etc. (set "Games you own" to Only)
