I haven't played a GC in ages. Most of my games start with Peter's 1520 modded with Daywalker's ai package. Makes for a much miore challenging game. Katsyev also has some good ideas. I just started a 1617 game with the ai package and its a lot of fun to see NA not completely colonized by 1570. Plus, the Dutch are in their heydey. A fun scenario to be sure.
