Concerning the installation :
I would also add the "bin" folder to the back-up list before installing as your installer changes files there too.
For an unknown reason the installation process bugged towards the end and couldn't complete (towards the maps and video part) but that didn't seemed to prevent the use of LOUD as I could launch and play the game normally.
All the backing files system makes it a bit painful to install as you have to be very careful and do a lot of cut/paste. So when you want to play with LOUD it is not an easy switch.
Also you cannot choose what files to install so for example if you don't want all the maps you cannot choose to opt out during installation process.
Other than that the installer did all the work downloading and installing the files.
Concerning units selection I had just a small comment with the caveat that I only played 2 games with LOUD, the AI when building Experimentals seems to have a strong preference towards TotalMAyhem units (and marginally BlackOps) as I don't recall seeing any MonkeyLord, Megalith, FatBoy or Collosus. Is this voluntary ?
Please let us know when you release a new version of LOUD AI.
