Here's my updated take on the game as well after managing to win each of the four brigade scenarios. I'm with Bill. I LOVE this game. Pierre and anyone else who has ordered it won't be sorry, especially for $20. As Bill says, the game is real time, so five seconds in real life is five seconds in the game. Most scenarios can be played out in about 45 minutes if you follow your orders correctly. If you don't, it could take much longer. I was routed as Burnside and had to rely on other Union brigades to clear my objective area of Rebs before I could rally my boys and then limp forward to take possession. That one took about 1.5 hours or so over two sittings, but I learned my lesson! I haven't graduated to the Division or Army command yet, but my understanding of the way it works is that you must send couriers to any of your subordinates who are located greater than 50 yards away from you. Apparently, if you try to micromanage regiments at these higher levels you will more than likely lose as other areas of your lines go neglected.
The graphics are pretty good, especially when you consider that this game was created by two guys in their spare time. And as Bill also mentioned, this thing is wide open as far as modding goes. The designers were even kind enough to place everything in .csv (spreadsheet) and text files to make the modding that much easier on everyone. There are a few glitches every now and then with the AI. I once saw a Rebel courier (I was playing as the Rebs, using Evans' Brigade) go through my lines and disappear somewhere behind the Union lines facing me. I did see him come scurrying back quite some time later. It is my understanding that they wish to eventually make the map editor easier to use and eventually release it to the public. As of now, they are actively looking for people to create Second Bull Run scenarios. I think I might give it a go if someone else comes up with a useable order of battle. My only problem is that I've never been able to find decent regimental strengths for Second Bull Run.
Anyway, I've rambled on enough. After I've moved on to Division level (one or two more Brigade-level wins oughta do it) I'll give my impressions there.
