It’s not terrible advice tbh, even just hand sketches are solid for getting ideas down, makes it easy to translate to cad. It at least helps me think things through and the like.
Get a few pencils with different leads (some harder stuff like 2-4H and an HB) and some nice paper and you’re good, but really anything works, totally have a mockup of my garage on a whiteboard planning where I want to put stuff.
As for cad packages, freecad, as far as I’m aware there are some architecture workbench plugins, and there’s a tech drawing workbench. Coming back to cad after a while I found it super easy to pick back up (coming from solidworks at least)
From the 360 Era — Too Human
The control scheme is bizarre at first (right stick is melee) but it works once you’re used to it. It’s Sci-Fi Norse mythology, I recall it having a pretty solid art style. I picked it up used from either Blockbuster or EB because I wanted to see just how bad it was, ended up enjoying it far more than I expected, I’ll give it a “Yeah, it’s ok”, disc images are readily available if you want to emulate it, can find a physical copy cheap online too if that’s your thing.
This is the game that ended up taking down its studio (Silicon Knights, they developed Eternal Darkness: Sanity’s Requiem and Blood Omen: Legacy of Kain, they tried to sue Epic, who countersued and won, probably added to my initial interested tbh.
