I've never played the Democratic Decay mod so I don't know which would be better for you, sorry. I made my version to be more accurate after someone pointed out that the UK doesn't have the same American-style lobbying. It starts with Election Laws and Lobbyist Restrictions to reflect this.

If I want to play as britain, and have all of these installed, would you reccomend the britain in the overhaul pack, or the one in the Democratic Decay mod? It bugs me to be constantly unsure if I'm playing a lesser version.
