View Full Version : How To Get Started with OSE/OSRIC on FGU?

I'm thinking about possibly starting an Old-School Essentials or OSRIC game on FGU. Before I dive in any further, I need to know if I can run them on FGU.
FGU doesn't seem to have a B/X/OSE or AD&D 1E/OSRIC rules system available when creating a new campaign. Nor does the Fantasy Grounds store return the OSE/OSRIC rulebook when I did a search there. How would I get started with OSE or OSRIC on FGU?

OSE rules are in the Forge.
https://forge.fantasygrounds.com/shop/items/199/view
ORSIC is a module that can be loaded into the AD&D 2e ruleset. Search the forums.
There was a AD&D 1e extension that worked with the 2e ruleset, I think it is still current.

Thanks, I found the rules! Didn't think to search the Forge - never used it before.
So, am I understanding this right: Is the way to play AD&D 1E in Fantasy Grounds to use the AD&D 2E ruleset?

Thiat is a link from the top sticky threads in this form. There is another forum for OSE as well.

Hmm... selected that 1E Extension and all the OSRIC content in the Forge (they are in my Inventory) but they don't show up as modules in the campaign I created with the AD&D 2E ruleset.
How do I "activate" the extensions? I've never used the Forge or extensions before, so I'm a total noob with these kinds of things.
Do I need to buy the AD&D 2E core rule books for this to work?

This is starting to get into how to use FG, and there are a lot of videos and such that are better than forum posts.
Extensions you turn on in the load screen for your campaign.
Modules are opened via the library button/menu at the right of your screen once the campaign is open.

Hmm... I can't see the OSRIC extensions in the load screen at all. There are just the usual theme extensions.
I know where to open modules but I have not bought any AD&D 2E books. Do I need to buy them for this whole OSRIC thing to work?

You create a campaign using the 2e ruleset.
Most of the osric content in .mod or modules.
I cannot tell if you saved these into the correct folders.

Thanks, they were saved through the Forge, but I didn't know that I had to press the update button for the extension and modules to load. Now I see them and have them activated.
I'm still unclear on if I need the AD&D 2E core rule modules? (Players Handbook, Dungeon Master's Guide, Monstrous Manual) Does OSRIC use those or does OSRIC work on its own?

The OSRIC books give you what you need to play OSRIC in the D&D Classics ruleset. Just make a new campaign, load the modules and the extension and away you go.
You will learn more by stumbling around a bit, so don't be afraid you can't F things up. :)

If you want to play 1e then I say play OSE. You can do basic which is BX or advanced which is 1e ADD. I did the ruleset and developed the tomes. You can try it out for free ad use the SRD on the Forge. If you have a potato computer then OSE will run a lot better for you.

As it happens, I've been looking at OSE as well :)
However, I was under the impression that OSE Advanced is not the same as AD&D but rather its own thing similiar to that style... Perhaps I had misunderstood? The main concern being how compatible is it with AD&D modules.

OSE is not AD&D just like OSRIC is not AD&D.

Which ever ruleset you decide to pick the Classic DnD modules in the FG shop are designed with 2E in mind (sometimes NPCs from the original module (ex. Basics or ADD1E) might have been readjusted to fit 2E or you might have to do it yourself if you are not happy with the conversion). There s a tool to convert 2E NPCs found in purchased modules to OSE as well.
OSE has a free ruleset and the free SRD includes basics DnD game (kind of red/blue box). Advanced OSE module (not free) allows you to plays very close to ADD1E(added races, classes, levels etc..) while still using the original DnD rules.
OSRIC is free (it includes DM, PHB functions, also has a MM) and is pretty close to ADD1E (you can use it with the free 2E rulesets and adding the free 1E extension to emulate the 1st editions slightly different rules)
2E has a free ruleset but everything else (PHB, DM, MM etc...) has to be purchased (currently on sale)
i don t know anything about 3E, 3.5, Pathfinder 1 or 2, Castle and crusades, DCC or any other post 2E rulesets...
'
At the end you can use a 5E modules in OSRIC for example and vice versa... all you need is to adjust NPCs...

OSE is not AD&D just like OSRIC is not AD&D.
No, but one is designed to emulate it and the other is not. So its a range instead of "just like".
If you want to try to make an old school campaign that runs like B/X with stuff used from the AD&D 1E PHB, then OSE is a fine choice. If you want something that runs combat and other game procedures more closely to how they're presented in the core 1E books, the OSRIC modules will be more satisfactory.
All you need for an OSRIC campaign in FG is to start a 2E campaign and then load the OSRIC data modules instead of the 2E book modules.
Keep in mind that the 1E AD&D modules sold here are built to use the 2E modules. So you might have to tweak them (replace monsters in the modules with OSRIC monsters, etc.), and they don't all work with the 1E extension - at least, in a test game I was part of that ran N1 Cult of the Reptile God, the combat tracker only worked right with the monsters built into N1 when the 1E extension was disabled.

Apologies for the inconvenience, and thanks for the report. This is fixed in the forge. You'll need to check for updates from the launcher.
