Bonus post for Swords and Wizardry Appreciation Day!While looking at my PDF copy of Monstrosities, by Frog God Games for Swords & Wizardry, I came up with the [probably obvious] idea of a campaign based on encountering all the monsters in Monstrosities in order of Challenge Level (give or take a level or two.) It wouldn't take much, just a little planning and considering that every monster includes an encounter, lair or scenario, your players probably wouldn't know any better. It's probably best to have some sort of home base, a hex map of some sort (possibly complete with encounters and localities, I might use Blackmarsh or The Majestic Wilderlands by +Rob Conley).
Here's how I'd probably do it: (mind you this is all just in my head, and I haven't tried it yet.)
Print/Copy the Monsters by Challenge Level lists (starting on page 534) and roll a big die, probably a d20 or d30 (maybe even a d100) and count off until you get to a random monster indicated by the die. The big die is to add some randomness to the encounter level. A d30 would get you a monster from Level A, B or 1 if doing this the very first time. Read the encounter. If it works, plan to us it immediately. I'd probably complement this with a hex crawl. When they enter a new hex, 1 in 6 would indicate an encounter. Either the built-in one (if using a pre-made hex crawl map) or the monster you rolled (if it makes sense). You probably want to log it somewhere, and cross off the monster from the list. Especially if you want to get to all the monsters in your lifetime. Incorporating a developed hex crawl would give the campaign a bit more continuity. I'd cross off any monsters encountered in the the hex crawl from the Monster list, again to increase the likelihood of getting through all the monsters. If you get a monster that doesn't fit, the environment or setting. Pencil it in for later. Or the "next one" when the area is right. It's still technically random. Keep doing this, crossing off monsters. Starting the count from the first available monster on through. The CL spread should get wider too. There will be a lot of fiat, making encounters fit, but that's part of the fun. You can roll the next 3 or 4 monsters in advanced, and try to tie the encounters together. Some random dungeon generators would come in handy to expand or detail a lair.
