From simulation perspective Transportation DLC is probably a better idea than Energy DLC.
From gameplay perspective I think that Energy DLC has more content that Transportation DLC
Your statements precisely describe the current dilemma when it comes to potential new DLC development.
So do you suggest that the dev team should focus on improving the base game instead of embarking on a new DLC development, after the completion of the Banking DLC?
If so, which aspects of the game need improvements the most, in your opinion?
As for analysis mode, I think that in theory it is a good idea. Classic 3x3 grid is outdated and has to be replaced with better views and/or mechanics. Unfortunately currently analysis view is rather hollow. I still use 3x3 view almost all the time. Not because it is the future, but because it is still more useful.
Please explain what you meant by "rather hollow" and how it can be possibly improved.
I think that you should continue to make experiments with analysis view and advertise it among the players. One day it will lead to a new view that will effectively replace grid.
Currently there are little boxes representing stocks of products being animated in units in the 3X3 grid. When the 3x3 grid is gone, would you imagine that the game will become more static and actually less interesting to play? Also, it will reduce the amount of user interaction required for setting up and running firms, will that make the game less fun? In the majority of time, the player will be just analyzing tons of data. Once decisions are made, it will actually take only a few clicks to execute, if the 3x3 grid is replaced with something simpler.
