Oh that's hard to say. It rotates around depending on what I've been enjoying lately. Just gonna list a handful here tbh
Fallout New Vegas. Goes without saying. Genesis of the yeehaw in me.
Halo 3 & ODST. Bundled for convenience, but for a great many years these games were my go-tos for after school/weekend entertainment. The amount of times I've played Halo 3's campaign to completion... Ough. ODST has some of the Most Vibes in gaming.
Fable. The game that gave me problems [Endearing]. What a fucking soundtrack. Like genuinely go listen to the main theme of Fable rn. https://youtu.be/w4I23yxiJq4?si=kIkFbjPR15hJt-f2
Anyways there's a non-exhaustive handful of my favorite games ever.
