Open Gaming License(Redirected from OGL)
Open Gaming LicenseEdit
Introduced by Wizards of the Coast with Dungeons & Dragons 3rd edition, it was a rip off of the GNU Public License that made open source software so ubiquitous. The idea is that you can make splatbooks and derivative works without paying hefty royalty cheques, so long as you don't pass yourself off as "official" support material, and you let other people make stuff derived from your stuff. Plus US courts have held you can't copyright game rules, only the words used to describe them, so you don't actually lose that much.
Giving things away for free, even if it means you get truckloads of new content you didn't have to hire writers for, and it gives your product most of the market share, is still scary to execs and suits, so Wizards of the Coast "improved" the Open Gaming License in 2008 to the "Game System License," which allowed developers to use D&D trademarks like beholders, but forces them to stamp their products with WotC and D&D logos, and WotC can change the rules at any time without notice, and if they decide to sue someone the target agrees to pay the legal fees up-front. Understandably, authors said "fuck that noise" and stuck with the OGL.
Eventually Wizards realized (translation: copied from the greedy fucktards at Bethesda) that you don't have to pay writers to make lots of supplements if you let fanboys write them for you and take a hefty slice off the top, so in January 2015, they released the Systems Reference Document for Dungeons & Dragons 5th Edition under the OGL v. 1.0a containing just enough for supplement writers to write 5e-compatible books and created the Dungeon Master's Guild, which allows developers to use D&D trademarks (and settings like Forgotten Realms) but with Wizards taking half of all revenue and reserving the right to steal your shit to sell again as DLC for their licensed vidyas. This means that Wizards has successfully introduced the concept of paid mods to tabletop gaming, and this time developers seem to have taken the bait. At least you can tell them to fuck off and just use the SRD, even if it's the absolute bare minimum to work with.
When you use the OGL, the stuff that you don't want copied and passed around has to be explicitly stated (See definition 1e, and item 7 below "Product Identity".). Since Wizards retained all trademarks that can possibly refer what the hell something is supposed to be based on or compatible with, "OGL" also sees use to refer to what a system is. This would be confusing, but the exact nature of the OGL means there's no real reason to use it over a very similiar but legally distinct license if the product isn't ultimately a derivative of 3E D&D or, more rarely, d20 modern.
