Open source implementation of the Bard's Tale Construction Set, plus a lot of enhancements. I do the graphics for it. It supports 320x200 and 640x400, but I'm in the process of supporting 1920x1200 as well. Works on Linux and Windows platform, but games that are created with it that follow the BTCS format explicitly, will work on the Amiga version, without additional enhancements. Tried to find a developer for an Amiga fork, to no avail. It's fairly robust already. I've been involved with the project since 2009.

New Bard's Tale construction set is also epic.  I remember a game I bought called The Devil's Whiskey that was supposed to be a throwback to that.  but it required some really old python and I couldn't seem to get it to work right.  I should try again.

Devil's Whiskey is a really good game. You may need one of the patches that came out, after it's release. Dulsi, the coder for BTBuilder, was one of the coders for Devil's Whiskey.
