Steam game reccomendations

What should I get on steam sale? I'm probably gonna get Neon White.

dyson sphere program

persona 5 royal if you dont have it already
if you do, get hoi4 or CK3. Hoi4 has an incredible mod community and you can get thousands of hours of mileage just from challenge runs and using mods. CK3 Is moreso the same but set in like the viking age. I think hoi4 is better personally but CK3 is also fun in its own way.

outer wilds

play it completely blind though. dont look up anything about it. trust me this game is an experience
