i'm not good with this computer spec stuff, how the frick is this game 1 GB

I can write a 50kb application that would squeeze your CPU, GPU, RAM and HDD/SSD dry. Things don't need to be heavy to have an impact on your hardware.

The most size-bloating things in modern games are:
1) Coding frameworks, usually for several languages. Using several frameworks is usually absolutely not necessary, but their developers usually give no ♥♥♥♥♥.
2) Textures - People want 64kx64k hi-res textures with bump mapping, parallax mapping, subterrain surface, reflections and etc. That can easily go up to 4gbs with textures alone.
3) Sounds - High res sound and music weights some. if Valheim devs would decide to go full LQ - they can easily save up +50/100mbs on sounds and music alone.
4) Hi-poly models - People want 25mill polygon models nowadays + some model formats might be more or less heavy(Valve's Source and Source 2 mdl format are quite heavy, but simply because it is also a container for few other things. In Goldsrc, models used to also be texture containers).
5) DRM trash and other "spamy" stuff. You can easily get half a gig of that stuff.

If you give the same approach to most modern games(less premade but more generated stuff, less quality textures, less quality models), I think the most heavy ones(like the recent CoD that weights around 100gb) might easily be fit in 2gb.
