Good to have a list.
Pathfinder and Chaos Chronicles are our best bet for the 'IE experience' and are definitely the ones to watch. (Black Geyser has a long history of question marks over the basic competence of the developers, such as copypasting the POE UI then adding some hilariously broken animations, but hopefully it ends up proving itself in the long run.)
Chaos Chronicles died years ago, and I haven't seen any information about any revival of that project. Do you have some new information?
Oh, you are in for a treat:
This is the original CC developers, now able to develop and finish the game without interference from the morons who temporarily seized the unfinished assets and released it as shovelware to make a quick buck. This is the real deal.
Thanks! That is awesome. I was so very disappointed when CC died, especially because of the utterly ridiculous reasons why it died. I checked out your link and it sure looks really nice, including that they're actually using the D&D 3.5e OGL. That way they don't have to waste resources on developing systems and can focus on the story and the world and the characters.
