I'm really torn about this one. There aren't really any other games to take it's place, but I really don't like the direction they took. I know I'm strange, in that I liked some of the micro-intensive features of 3. OOB for example, which has been removed for 4.
I guess I'm getting the strong impression that I started to get with one of the updates for EU4, with colonial nations (and yes I know you could easily mod that out, but the game was balanced with them in mind). The devs seem to be designing the new games with multiplayer in mind. Now that's not a bad thing, but it does conflict with people who like to micromanage things and prefer in depth game mechanics. This wasn't much of an issue with EU4, but HOI is an entirely different sort of game. You don't need to micro your armies in EU like you would for Barbarossa, for example. It's not an issue for sp, you can pause and take what time you need. The solution for mp is to have a way for the ai to do the micro.
It wouldn't be a problem for me if it was an option to use the ai, but here it appears to be the way you are supposed to play. And the last thing I want to do in my free time is baby sit some incompetent ai's. I wouldn't play a game of EU4 as England and let the ai shape the new world, I want to do so myself. That's the enjoyment I get out of playing England in EU. I really wouldn't play a grand strategy ww2 game to let the ai manage my armies. From what videos I've watched, it's as though you grab some units, click a front, and watch a blob of one color eat another. Yes I know it's not that simple, but one thing that's worse than too much micro is having to micro manage ai's, for me at least.
For anyone looking for a ww2 grand strategy game, and who doesn't want to have to manage every detail, this may be the game for you. For people like me, probably not so much. I'll still buy it, likely even today because I'm stuck at home unable to get to work because of flooding, and because I will hope that patches/expansions/mods make it better.
