Lots of Interesting Decisions:
economy: spending, producing, refitting, entrenching, shipping, research, ...
military: deployment, limited transport and operational capabilities, multiple theaters, ...
Good Game Design:
feels right, credible representation of conflict and time
several historical options possible (research, deployment, diplomacy, ...)
interesting and fun implemented
I like the UI in the following departments:
visual representation of the units and relevant data (strength, combat readiness)
auto ordering of the stacks (i.e. HQ at the top)
info for all units of a stack readily available in a status box
color coded info on possible movement options (HQ supported or individual movement)
cancel last move implemented
Points that could eventually be further improved:
better mouse scroll (perhaps full screen mode, or selectable mouse lock to the window)
naval overview should be available at decision making dialog
menu buttons for each nation would allow for faster access (in add. to the drop down menu)
(should be also available in the R&D, Nation, Naval, etc. Dialogs)
Tips for starters:
the hint in the naval dialog about where shipping transportation should go is important
without shipping your economy will be crippled
cavalry is able to move into enemy controlled territory without HQ support
(look for the details in the manual)
I am enjoying your game right now. Also liked Campaigns on the Danube. Your games achieve a plausible and challenging depiction of the historical conflicts.
