SUMMARY
Bt Builder is an open source implementation of Bard's Tale Construction Set, a 1991 title that allowed ordinary gamers to build their own Bard's Tale games. It is presently at 0.5.7 and already has a fair amount of functionality to it. The programmers may also implement compatibility with the classic games "Wasteland" & "Dragon Wars." So, if you've always wanted to create that wonderful early Bard's Tale game but the original Construction Set won't run on your modern Windows platform or you want just a bit more functionality in your editor than the original can provide, your boat may soon be arriving... Eventually, since it has been in development since January 2007. The best things come to those who wait?
