Yeah, I really enjoy it. According to Steam I have 322 hours into M&B. Within a couple of days of plain, and I liked plain, I just was reading forums on the game and the Floris mod was highly recommended. As was the Diplomacy mod (which is in Floris). So I installed figuring if it sucked, I could get rid of it.
Since Floris was a win, I never did the Diplomacy only install. And I never went back to plain.
