I just bought Brotato for like $3.74, because I just finished 100%ing Vampire Survivors on my Steam Deck.
Mandatory you should own Stardew Valley by now, and his big v1.6 update finally comes out next week.
Hades is on sale for like $12.50. It's on sale for $12.50 more than it's not on sale, really.
Red Dead redemption 2 and two spider man games are also on sale.
Really, it's a steam sale. Just buy everything that's at least 40% off till you're broke. My backlog is probably already bigger than I have years left.
