Since it's a completely different game, I don't think you can compare...
So what exactly IS different from army point of view? Look at the videos. This point is exactly the same!
And trust me from single player aspect I'm just disappointed from the AI at all.
They all add features over features over features in these games and on the end I just ran over everything because I USE THIS FEATURES and the AI not.
WoM/FE, HOI/EU/Vic/etc., MoO, MoM, GalCiv, Civ, AoW, etc. pp.
All have the same problem. While UI and "features"-additions improve a lot during years. AI not. I want to react to something, instead doing the same all the time works perfect... (no need of big tactics, just "exploit" the things the AI doesn't do/the AI can't handle). And I don't talk about complex strategies/tactics which should be exact the thing the Human should do to get rid of the AI bonus in hardest difficult level, I talk about very simple things that work to win (iE creating 1 Killer Stack, getting easily bad defended cities in the hinterlands, just FOCUS opponent units&HEAL my units, etc.).
In some games I feel like adding a "cheat command" just by creating a stack with a lot good units and the AI can't handle (1 "Killer" Stack running over everything).
In HoI3 I use the Theatre-Mechanic by setting everything to AI control and don't move a single unit by myself to limit me somehow to get some challenge at all.
I'm tired of games developed for all the Testers around who have fun for 2-3 hours with all the features and missing the fact that players want to replay the game and want some challenge after 1-3 games and not just collecting the features and win...
