ACW has not been my favourite period to game in the past, although I have read a decent bit of the history. UGCW has changed that and has been a great experience so far (still playing through my first campaign). I love the battlefield tactics part, which are generally easy to understand and adjust to, and look fantastic. I also love the campaign, with the experience of dealing with major decisions of where to focus, medicine vs logistics vs politics, etc. I spend more time in camp than in battle, but it is all very interesting, knowing that what I do will soon be tested in battle.
Congratulations to Nick and the studio.
I hope in the future to see them tackling events of 80-50 years earlier, which would be spectacular.
