We should discuss about what is missing in AGE engine for RUS, in the dream where a RUS 2.0 (patch, or sold as a new game?) could be released with a new engine.
What I noted or saw:
. Units faction can't change (whole regiment could go by itself to the ennemy or allied).
Grigoriev switchings could be a bad example, as it could be a faction by himself, but some Red regiments had joined makhnovists.
------------------------------
My secret recipe for my own game (which shouldn't be released finished someday..): Regiments can be lead, compelled or not, by general of another faction. Faction owning it depends of which is stronger (by propaganda or/and State military police and/or "bread&games") between regiment and leader. Propaganda could make regiments prefer other faction, and may switch if some prefered leader is near (killing or rejecting past leader). If no set faction can compel it, the (Green?) regiment may organize itself and choose a general in its own ranks (the Leader could be from another faction, but at start less strong than his regiment).
------------------------------
. Countryside can't feed people (units should be fed by town only if country can bring food to town).
The rich farmings of Ukraine should easily feed units if paesants are not too reluctant (not becoming Green).
. Special Operations are unprecise: http://www.ageod-forum.com/showpost.php?p=206340&postcount=57
I know there are tweaks to 'adapt' (Black becoming Red in beta patch), but the system is still not so good.
