I think the most satisfying part of the game for me is improving the efficiency and throughput of the factory, but, unless I’m mistaken the stats overwrite themselves relatively quickly and its difficult to see far into the past to see how much the factory has improved over time
If its possible it would be great if more graphs and stats for longer (whole game?) periods of time.
Also maybe some additional graphs for things like like average profit margin per car, percentage of car from imported vs. produced parts. Graphical stats for flow time, and value added time vs. nonvalue added time on the floor.
