All of my stuff is digital and organized by my own chaotic brain, so idk if I'm the target audience. However, I've been learning GURPS for a few months and it's very interesting compared to the Pathfinder 2e system my friends and I have been playing for years. You could try going over to that sublemmy and ask there.

i run a game of Beam Saber and i'd love a premade notebook to keep all the clocks/factions/squads/relationships/npcs/regions straight

currently using a digital spreadsheet, but i'm an analog person so i'd use a notebook if one existed

Very fun game. Highly reccomend Beam Saber if you want narrative crunch and like mecha

what seperates a normal notebook from a campaign notebook?

if it's a book/folder full of templates to fill in:

• dungeon templates, probably a 2 page spread, with space for map, numbered and otherwise empty squares to uses as room key + description of the rooms and a 2d6 random table to fill in.
• space to describe a bigger region (name, capital, system of goverment, list of subregions like cities, forrests, etc. with a reference to the filled in templates for those regions)
• templates for cities, simmiliar to the dungeon template
• wilderness template with a bigger focus on space for descriptions and without a drawn map, but maybe multiple 2d6 random tables to use for example as day and night encounter tables.
• 2 page spreads consisting of 3 lists containing 6 spaces each on every page. i'd use that to keep track of npcs, left side allies of my players, right side enemies or neutral parties. that way i can use those tables to generate random events involving npcs if i don't have a cool idea for a session. I'd roll a d4 to determine if i use an npc from the left or right side on a 3 or 4 i'll use npcs from both pages, but on a 3 the left side npc is doing something to a right side npc and on a 4 vice versa, if i can't decide from which list to pick i can roll a d6 for that and if then cant decide which npc to pick, i roll another d6.

and i think those templates could be setting and system agnostic, an alien space ship is as much a dungeon in the rpg sense as a literral subterranean dungeon, and a wilderness could be a canyon on mars or the swamp next to an evil wizards lair. Setting here would be more for trimmings like dragons perched on top of tables or lists depicted as output on a computer screen.

hmm there are probably multiple cool ways to setup lists and tables to assist in writing your own random generators for various things...
