I'd like to take advantage of your willingness to help out! After loving the game since the demo came out, I'd like to just mess around with it and fiddle with money and resources (possibly also research and construction times). I tried installing the Developer Mode mod (http://xcom.nexusmods.com/mods/363/?) but Steam basically told me the whole thing was corrupt and had to redownload and install the whole thing. What am I doing wrong? What's the best way to achieve what I'm trying to do?
