From my own personal experience, the mod is enjoyable to play. Moreover, the mod receives plenty of updates and bug fixes and has obtained positive reviews from fellow gamers, despite some important nations missing unique focus trees. In essence, the Road to 56 mod basically enhances what you get in the standard vanilla mode. With this, the mod includes more units, a developed troop experience system, laws and new releasable nations.
There are no prizes for guessing that the game runs until 1956 as opposed the shorter time the vanilla mod runs until.
This mod looks to balance the overall gameplay of the game by offering more unique national focus trees to nations such as Brazil, Tibet and the United Kingdom allowing you to explore different historical paths.
