I've played AGEOD games quite a bit, and have all of them, but this is my first grand campaign for CW2, so I thought I would share my impressions.
Overall, I think the game does a great job of simulating the Civil War. In an earlier post I complained about the AI attacking in weird places and/or weird behavior, but I've worked around that as best I can. There are frustrating parts, but these are, I think, what the real commanders (like Lincoln) faced. First, the inability of Union generals to activate so you can do anything with them. In the early war, you're stuck with such luminaries as McClellan, McDowell, Fremont, Banks, Buell, etc. All poor, and all who spend more time sitting around than attacking. Then there's the battle results, which can be bewildering, but so were the real ones as well. God isn't always with the bigger battalions.
The hardest thing is organizing your forces and, of course, logistics. But taking a very small peace time army and making it into a very large, effective one is quite a challenge, and I think the game models this well. Many first time players have complained about this, but this isn't a beer and pretzels game. It takes real work to recruit, train and organize your forces into divisions, corps and armies, and I find that's it's actually part of the appeal of the game. Logistics are always a headache, but again, realistic, so I think the game models this well.
The scope of the game is mind-boggling, both in terrain covered and in what a player actually has control over. And that again is what makes this a great game. And yes, I do have Grigsby's game and FoF as well. They don't match up.
So far, I am very impressed. Some things could be better, and I am sure will be improved over time, but those who walk away in frustration after a few turns are missing out on a truly great game that will reward with hours and hours of enjoyment once the concepts are nailed down.
Thanks, AGEOD!
