GURPS Basic Fantasy: BF1 Morgansfort

Basic Fantasy is one of the most amazing projects and games ever created. Free for everyone to play, a hybrid OSR game that mixes the best of modern mechanics with old school gaming. And the one part most overlooked is that this game was tested extensively, and the math just works flawlessly. People will play other OSR games and come back to Basic Fantasy just because the math and balance are solid here, and there's no wonkiness or silly stuff that breaks immersion.

And the books are free for all to enjoy.

It is one of the most generous communities in gaming, and the books are printed at cost and sold for zero profit. This isn't some $200 botique OSR game meant for crowdfunding profits; this is a movement to keep gaming free for everyone, forever. I wish more communities were like this one.

And this is one of my favorite systems to convert to GURPS. No offense to the creators, these adventures are amazing in Basic Fantasy and should be played there, too. But as a GURPS adventure engine, Basic Fantasy is a snap to convert adventures into GURPS, the AC values cleanly translate into DR values, and you can even use the HD and hp numbers nearly as-is in a hybrid conversion model.

And the adventures, towns, maps, and worlds are so well put together, they are amazing. There isn't too much detail, but there is just enough to get the mind working. They are the perfect blank canvas to work on, not so blank that they are nothing, but with just enough detail to expand and fill in yourself.

They also feel on the low-fantasy side of the genre, where magic is still rare and special. I could play these almost entirely low fantasy with GURPS, even without magic, and they would work perfectly. I like being able to control how much magic is in a setting, and I have a few setting books that overdo it with the magic to a point where the setting feels unusable.


Converting

BX hit points and damage are very compatible with GURPS, and if an orc has 4hp, let him have that, and he becomes a BX-style mook in GURPS that typically goes down in one hit. I am not looking for everyone to have 10 hit points in GURPS, and 1-2 HD creatures will often have less, but by the time creatures get 6+ HD, they will be tougher in GURPS, almost like boss monsters, and it will all balance out.

If a basilisk has 6 HD in BF, that will be 6d6+12 hit points in GURPS, or about 34 hit points on average. a DR of 5, and ability scores of about 16. Attack skill will be 17, and powers that total 30 character points. I have a B/X conversion page that works pretty well. The only difference is that converted creatures will be a little tougher at higher levels, but if you treat them as boss monsters, they will be fine. Lower-level creatures will go down fast like mooks, but that is fine in the genre, too. GURPS is deadly enough that a 2 hit point goblin with a skill of 12 can kill you pretty quickly on a critical hit with a shortbow.

Mind you, get access to one high-tech firearm, and even that 9 HD dragon with 63 hit points, a skill of 20, and a DR of 9 is going to go down fast. To those with bows and pointy sticks, that dragon will be terrifying and take dozens of men's lives and a few siege weapons to take down, if it is even possible, or the dragon doesn't flee early.

This is a converted reality versus the actual baseline GURPS reality. The world will have that "video game" feeling in places, but this is how the gods decreed the world, so it shall be. GURPS Ultra Lite fills in most of the rest.

My conversion is more "GURPS in a BX reality" than "GURPS in a realistic reality," where GURPS drives the engine of a BX-style world, BX values are imported from standard bestiaries, and the differences between high- and low-HD creatures create a natural balance. There will always be "hero orcs" generated like characters, but the rest are background extras in a Peter Jackson movie, left with their converted HP and HD ratings.

This also saves me a ton of conversion work, while leaving the door open for me to create custom hero monsters with the character creation tools. Oh, and kudos to the GURPS community that does these amazing conversions! If you want to play with "real reality" stats, please visit those sites and creators and support the amazing work they do.


The GURPS Campaign

I would start in Morgansfort, even as just a hired bow guard on the walls, and run a campaign telling his story. Since there is a refugee component to the setting, with new settlers arriving, I would expand the fort by adding wooden houses huddled around the outer walls, and place the newcomers in them.

The castle itself is a bit small for a few hundred people, and putting them gathered around the fort for protection makes sense. There are humanoid attacks, so the fort's defenders would ring a bell and rush everyone inside before slamming the gates shut. This puts pressure on the new workforce outside the walls to be digging an outer defensive moat with pikes, and putting up a temporary wooden wall before a large outer stone wall can be constructed.

There is room for it on the local map, and the cliffs on the water could be left open for now. There could be an argument on how large the outer walls should be, if they should stay 120 yards from the fort, or extend out all the way to the road. The scattered farms would also need to be considered, and they would need to expand dramatically in the near future. We need the wall. The humanoids keep attacking. The refugees are not safe out there. And we need to keep everyone fed and productive while putting every able-bodied person to work.

And that is it.

That is the campaign.

Keep it simple, use the included dungeons as a source of adventure, but leave the main story of the first few months, the building of the wall, and all the struggles around that, along with fending off humanoid attacks and finding their source. Keeping the game simple will ensure its success, and give me room to go any way I want with it. If the players want to train soldiers from the new arrivals, great. Do they want to direct the construction of the wall?

Do they serve as peacekeepers and constables among the new arrivals? Is there tension among the refugees, or between them and the town? Are the workers cutting logs getting attacked? Are the farms being raided while starvation looms? Is there a clan of dwarves in the hills who could help with stone, if they get help (or gold) for their services?

And since this is BX, could the orcs or goblins be negotiated with? Turned against each other? Could you find a good dragon who could scare them off (in trade for a favor)? Or perhaps find fae and get them to help, and not attack those cutting trees down for the town?

Keeping the starting point simple ensures longevity and playability.

It also gives the players the freedom to go in any direction imaginable.

Some may just want to "up and leave this dump."

Others will stay.

Some will head out to learn the secrets of magic.

Others will eventually make this the seat of their new domain.

That is fine by me.

I don't need "the magical stairs" and the "1000-year curse" with the "planar concordium" coming into play here. Some 5E modules go way too hard on the planar, multiversal, and high-magic stuff, and they lose me. I do not need any of it. I want humanistic, relatable, down-to-earth stories of struggle and sacrifice. In 5E, my characters would get so powerful that they would cease to care about Morgansfort. This is 5E's problem: You get so godlike that the world is beneath you. Why would the town ever trust people who get planar bastions at level 5 and are never seen again?

In GURPS, I can have an 800-point character who still cares about this place. That character is still very grounded and real to the world. While they may be around the world on adventures from time to time, this will always be home, and they will never outlevel it.

That keeps me coming back to turn the next page of adventure.
