I have no idea how soon it will be released, to tell the truth. I recently got in some personal difficulties, not to mention swamped with uni projects, so work on it lately has been non existent. I'll try to do some more during the week break that just started now that I cleared midterms, but I'm not making any promise, there are lots of other projects I am working on, too.
I'm not going to give any ETA, simply because I have no idea how things will turn out.
The last thing I was working on is refining the tech tree (actually finding NAME for some of the techs that lead to units is hard - I know where they are in the tree, I know what they lead to, I just don't know what to name them.
I also reworked to an extent the set of units to make it more enjoyable as for the number of units available to each civ.
