it's great to learn about your efforts of continuing development on a fork of what was so far known as Glest originally, then forked into MegaGlest.
Please note that Glest 2.0 was released in 2006 - https://sourceforge.net/projects/glest/files/glest%20source/2.0.0/
- and that picking "Glest" as the name of a 2nd-order fork of an original game which carried the same name may (understandably IMO) not resonate well with the original authors. I recommend choosing a unique name (unless they agreed to it, of course, but then it would seem wise to pick a version number above of what Glest and MG used - maybe start with 3.5 or 4.0?). Also, (while I can understand the urge to unify things) source code copyrights need to be retained - can't be inherited despite the libre license.
This said, it's thrilling to see someone is spending efforts to continue work and improve upon this game (even with the old engine it is nowadays). So I wish all the best to your efforts!
