The Legacy Map Pack is particularly key for new backers to allow them to play on all 40 missions. These are the original beautiful maps from 1st edition but revised for better tactics, more balanced openings, better pathing, and more useful on map cover. While still useful for Veteran Backers the Legacy Map Pack is not essential for Veteran Backers and more of a quality of life improvement since the 2nd Edition Update kit provides map conversion tiles that transform your 1st Edition maps into the improved 2nd Edition versions. Also includes revised and improved World Builder Map Tiles for total customization possibilities.
