Kalajel's free games and resources 2: The sequel

Hello everyone,

I was asked on the Discord to clean up my resources and free games thread (still available here), and sort the links by categories. I figured a brand new thread was the best solution for it. So this will become the new free resources and games thread. I'll still use the old one and sort through the links there to classify them here, but eventually, the old thread will slip into obscurity (or I might delete it, I don't know...). So without further ado, let's start this (thought the next posts will most likely be placeholders for now)!

(Note: Concerning the dead link for the Adventure Time game based on D&D 4th, I checked the pdf I had saved of it, and the creator left his e-mail address in it. It might be worth contacting him and get a pdf of the game that way: ilitchev@gmail.com)

The creator of the game is currently receiving a lot of flack in his reddit thread for having ripped off a bunch of tables from a variety of other systems and including them unchanged in his game. His last message was that he was going to consult with a lawyer...

Someone on Reddit made an exhaustive list of RPGs designed for children. While most must be purchased, a small amount are either free or PWYW. Even those which can be bought, some are pretty darn cheap. There is also a link for RPGs aimed at teens, but this list is less exhaustive and contains less information (such as which is free and which is paid).
Speaking of RPGs for children, there is The Cloud Dungeon which is not on the list. It is free-ish, you can either purchase it or get it for free in print-n-play format. There is also A Perfect Rock (also not on the list) which is PWYW on itch.io.

Ye Old Map Maker. A Flash-based online map-making tool. Though it is possible to buy versions for your various mobile devices...

Do you need modern maps? This site allows you to download Googlemaps with all the google labels removed. You can even choose different styles. Snazzymaps does the same thing, but it has far more styles to choose from and can also keep labels should you need to keep them. Meanwhile this other site will draw the entire road map for your selected city which can later be customized. Beware that the road map is somewhat pixellated and the customization options are very limited... Also, seems like you can already edit your own Googlemaps on Googlemaps by adding and editing layers. You can even change the style of the map. I tried to fiddle a bit in it and found it rather unintuitive, so the other sites above might be a better option for some of you.

Speaking of western games, I recently found a trove of western sayings, expressions, and lingo on many sites, too many to list off here, so I'll just leave the google results here and let you check those sites out yourself...

Downloadable goodies for Realm of Bethica RPG.

The Paper Demon app. I haven't signed up, so I'm not entirely sure what this consists of exactly, hence why I put it in this section for now. Seems you can draw your own character using prompts, so AI art? You also have a writing portion which I guess is for your own background, or perhaps even creating adventures. The thing that confuses me are the XP and treasures part which seems to indicate there is some sort of game mechanics involved in this. Perhaps even an entire game onto itself?

Curse of Strahd Reloaded. A way to make Curse of Strahd less... bad.

Online Dice Rollers
A bit of a joke on my last thread... Sure, you won't need 'em here, but what if you need to game in real life and forgot your dice (okay I'm stretching a bit here...).

Gone but not Forgotten
It is the nature of the internet that some site dies. While I can use the waybackmachine internet archive to repair some broken links, others will have never been saved in this archive. Perhaps other types of internet archives exist out there which could have those sites saved, but I do not know of any... Basically, this post will be used to list dead links, just in case someone is a bit more internet savvy than I...

Edit: Turns out there is another internet archive out there. Archive-It which searches using keywords instead of URLs. For exemple, I've made a search with Dungeonslayers here.

Suggestions and Comments
From this point on, posts are for your own suggestions, comments, or to warn me that such and such link is dead... I might post here as well from time to time to inform you of any update. I'd really like this thread to be a bit like a wiki where everyone could maintain it, but that might be outside of the site's capabilities... So the best option will simply be to allow you to post from this point on.

Nicely done Kalajel!

Great job, man. I'm going to be sure to bookmark this.

Here's a link to a list of SRDs for many popular systems.

So yeah, so far I've noticed that in my old thread I had a few duplicate links already. Going well so far...

A suggestion would be to create a "Table of Contents" with links in the first post. That way you can just click what sort of thing you're looking for and go straight to that post.

Two first page of my old thread have been transferred here. Going well so far, though I did found a few more duplicate links...
