The site is misleadingly titled SteamGames.com, implying a connection to SteamPowered.com (which is famous for the Steam launcher), and this page does redirect to that page, but they are not actually the same thing.
SteamGames.com is a fraud which steals money from random cards. It stole $50 from my mother.
SteamPowered.com is a game store & library. It is where I bought Skyrim.
