Maybe it is never too early to talk about another sequel, but it feels early. Even so, while reading the discussions in the improve CW2 forum and the modding forum, I've developed a set of desires I want to get off my chest.
Basically, playing the game, working on my mod(s), and reading the forum have taught me that there is a different civil war game that interests me. This other game is a game where creating and organizing armies and deploying generals is even more developed. I want to piece together regiments into brigades as governors notify me that regiments are trained and are ready to move into a theater. I want some regiments to vote for colonels, some governors to ask I use someone, to get to choose some myself, etc (majors and lieutenants within regiments would be out of my hands). I want the name pool for officers to be very historically accurate with officer abilities to be historical with randomization optional and improvement with experience. I want to asses battle performance and assign colonels to brigades when I can (and seniority to decide these issues at other times). I want to see generals request promotion for subordinates and to have to pick out generals for promotion from those who are and who are not praised by their superiors. I want promising leaders to die tragically. I want detailed information about regiment, brigade, and division performance in battle. I want information about these things to trickle in somewhat. I want less graphical slickness and more space in the game for tables and text.
I love how close the current game is to this, but the more I get into the guts of it, the more I wish the game were just a little bit different in ways that a mod can't really help.
Of course, another major direction of dream development is to expand the tactical aspect of the game to include a tactical battle sub-game onto the basic game (like Total War or whatever). This difference between AGEOD games and TW games that really intrigues me is that in TW, I never really cared about the sub-leaders and hierarchy of regiments/brigades/armies. When playing a TW game, I want it to be bigger, which is a very simple desire - if hard to satisfy. One great thing about this game to me is that it opens up a large number of very complicated desires.
