What is your favourite game?

Depends on what you're into, but some good options are Skyrim or Fallout if you like RPGs, Garry's Mod DarkRP is a cheap version of GTA online that is best for long (3+ hour) binges of gaming for the most successful experience, but granted it is a bit toxic. Serious RP on Gmod is also pretty good if you're into it.

Other options, I mean, CS:GO is pretty decent in my opinion. Also any grand strategy games by Paradox Interactive (namely HOI4, CK2, VIC2, EU4, and Stellaris) are great for playing long, drawn out games, and are really immersive to some extent.
