They sell the old games, they are not free. All of there games are overpriced and never go on sale, probably because it seems like they only have a handful of games.

I don’t think it’s fair to say valve is late to the party, if anything they are first. There is a distinct difference between consoles games and pc games, the steam deck focuses on bringing pc games to a portable format, that opens the door to an almost endless supply of cheap indie games, as well as the potential for large AAA titles like Assassins Creed. The best part? Unlike Nintendo or PlayStation you don’t have to buy the game again if it’s already in your steam library, outside of Xbox play anywhere it’s the first time players don’t have to repurchase a game in order to play it on a portable device.
