Eldritch Horror (bgg) seems to be the game-du-jour of my gaming crew as of late (even if we can’t finish a playthrough in one evening). EH has lots of fiddly counter bits, which, as of now, I’ve stored in ziplock bags of varying size. There are some better / nicer solutions.
Well, it appears that my craft-fu is a bit old and atrophied — this ‘turned out’ ok as a ‘first attempt,’ but really isn’t very aesthetically ‘nice’. [It fits in the EH box, and I think all the components are going to fit, too, and that’s the main goal in the end.] Some practice making these kinds of inserts undoubtedly would (will?) produce nicer results.
In any event, if you have a game with lots of fiddly little component bits, you should really check out the Esoteric Order of Gamers — they have compiled an enormous list of game-component-insert instructions and other “High quality materials for the dedicated devotee of immersive, thematic tabletop games.”
