The majority of the games I suggest in these daily posts are not free games. Their prices can be found if you click their name as that is a link to Steam where you can buy them for their respective prices.
The prices are quite varied. Sometimes they are f2p games, sometimes they are small indie titles for less then 5 USD, other times they are AA titles for around 20 USD but sometimes they are fully fledged AAA titles that can cost anywhere from 49.99 to 99+ USD.
