its like 4000+ books with 1000 pages of code each :))
W/o jokes: it was reinstalling of some huge files with a little changes.
The game is super polished. As in, aside from bugs and minor balance issues, this is the game they intended to make.
Please dont mislead costomers. DoS1 with minor changes, new story and map, with old bugs, same UI problems, bad economy and same major balance issues can not be truly DoS2. It could be new animated movie or gamebook with good story but not THE TACTIC RPG.
