I (try!) to play Great Invasions und without the knownledge that WW1 uses the same (improved?) Engine i buy this Game with a lot of interesting concepts. Bad idea ... will take a lot of patches as for Great Invasions to make it playable ... next time i will be warned
After all (unforeseeable?) reasons its not fair to sell a Game in development, without a full manual and rules that are not fully understandable.
