Alrighty then, v1.2 is up. Good post, go first post.
Main difference from test versions is that a). all groups will appear with unique names in the english version (this may have caused stray text symbols to appear elsewhere - if this bothers you, delete the customize_us.le_strings file); b). "Unethical" build has been reduced to a compilation of the first 2 builds (with a bit of civilians), and has the same number of characters - 81.
This means that the only characters that may cause troubles with deleting/updating GPO are DLC ones, and only if you choose to install them in the first place. Also, everyone, except brutes, Olegs and Killbanes, is recruitable off the streets, even DLC chars, and even if you have the Penthouse pack.
The downside is that with the way the groups are now organized, it's even more of a post-endgame mod than before - you will have to complete activities to get to the main course of each build.
