An update, 7 years later:
The Kickstarter to get MapForge made was a success. The app got made, and this became the website for it. The app can be used for free (in low resolution), or you can purchase a license for a one-time fee.

Over the years, many follow-up crowdfunding campaigns allowed further development of the software (e.g. adding support for hex maps and isometric maps, in addition to top-down maps) and tons of content was developed for use in the app, covering all major genres (Fantasy, Modern Day, Sci-Fi, Post-Apocalyse, etc.).

There are currently a staggering 237 content Add-Ons for MapForge (!!!). 60 of them are free, the rest are commercial products, with prices starting at $4. Most Add-Ons are for personal use only, but these Add-Ons allow for publishing and commercial use.

You can download the app from here if you'd like to try it out. This page will give you an idea of how often updates are released.

I think that about covers it. Oh, and a few years ago, I also created a companion app called TileForge, for making geomorphic tilesets. Similar model in that you can try it out for free, and a one-time-fee license unlocks high-res output.

Astral was partnered with OneBookShelf (OBS), the parent company that owns DriveThruRPG. After OBS announced its merger with Roll20 in July 2022 it became clear that Astral’s fate was well and truly sealed.

FoundryVTT V10 was released August 31, 2022 - and still in very active development

License cost is $50 USD, one time purchase

The project was released by the developers and the community took over.

You can find the new community edition here: https github(dot)com/ndo360/JParanoiaRPG

SceneGrinder is an immersive 3D Virtual Tabletop (VTT) with unique features, like first person point-of-view and interactive NPC's that you create. Our system is 100% browser-based, with no application to download or server to set up. Runs on desktops, laptops, phones and tablets.

SceneGrinder is the only VTT that enables you to build a world where your players can login 24/7 and play with or without a GM.

Over the last six months, test groups have logged hundreds of hours on SceneGrinder, helping us to iron out the core features.

The product is in Kickstarter pre-launch.

Visit r/scenegrinder for details and site information.

FoundryVTT full release was June 23, 2020 - Still in active development
License cost is $50 USD, one time purchase

There have now been three updates this month, including free tokens and a new die-rolling feature for Modiphius' 2D20 system. I think this VTT should be moved to Actively Developed.

Development may have halted, but there's a "service outage" note on the site as of 2020-03-29. So someone's at least keeping it running in maintenance mode.

I wanted to add a link to Shmeppy.com.

Added page for this new VTT, along with links in the sidebar.

The Fantasy Grounds Unity beta began on October 29, 2019. There are 8500 beta testers (those that backed the Kickstarter), and there were a dozen or so of us on the alpha team (higher Kickstarter backers).

It's all very exciting with the addition of dynamic lighting and in-game map-making on the fly. There are MANY more new features.

The scheduled release is year's end.

For more info, drop by their forums or Discord server.

TokenTool is a few token maker available on the rptools.net web site. You simply drag an image into TokenTool then select a framing element.

RPTools released MapTool 1.5. It now has bundled Java so most of the Java version/updates should be solved. The release includes Hero Lab and PDF integration, a new Macro editor with syntax highlighting and code completion, terrain modifiers, and Draw Explorer enhancements. The new release does limit movement based on Vision Blocking Layer (VBL) and Terrain Modifiers.

The announcement post on their site details the new functionality.

They added a Discord Server to help with live support.

Much appreciated!

I'll add it in the coming week.

I am working on a vtt at imetatroll.com. The site is still in beta, but I would appreciate it if you could add something to the wiki.

While there is yet much to do the following basic features are in place:

• Game creation with full support for video/text chat.
• Map editing with unique terrain pixel art that provides three levels of depth.
• Drag and drop creatures and structures.
• Hundreds of beautifully recreated pixel art monsters, creatures, humanoids (etc) as outlined by the 5E SRD.
• The entire 5E ruleset is fully searchable. Add spells to your character with a single click.
• Tablet support to some degree, though this does need a lot of work still.
• And more…

Skirmish have been added some time ago

Mote have been added to the wiki some time ago.

Still sounds about right.

I've added and updated 90% to get it more up to date orver the last half a year, but there are still much to be added, here is to-do list I created.
