What don't you like about Lunatic, if you don't mind me asking? I can understand why you removed the other two.
I also like the three maps you're adding. String Theory impresses me, that's a really solid map (though I still like my original version, Chaos Theory, better - creator's bias
). Iskander has some small stalemate concerns because of all the high terrain, but I'm not overly concerned because of the base setup and transport routes. Defiled Logic played kind of weird the one time I tried it, but it was an altogether fair and enjoyable map.
Thanks for the work you guys are doing.
