Well, I feel that I must take back the things I have said about EUIV's 3D world now that I've seen more of it. At first glance I thought "Oh, it just looks like Crusader Kings II now" but EUIV does look quite a bit better than CKII, I have also now seen the trade route map and I just think it looks awesome. So yeah, case closed, the 3D world looks awesome; I was wrong. It's rather nice how my opinion has changed.
Thank you, there is quite a bit of difference. Nice of you to notice.
