Hi! There are 7 countries at the time of writing. Calculations used for the benefit factor are as follows: round(log(user->land)/log(1000000)/2, 2) for a detailed graph, see: https://www.wolframalpha.com/input/?i=plot+%28log%28x%29%2Flog%281000000%29%2F2%29+between+1+and+1000000 This should give you a range from 0 to 50 in terms of discount or modifying value. This means, if you get attacked, and your land decreased, your modifier value will decrease as well. The same goes for land exploration. If you explore a lot of land, your modifier should increase. Note that with the above calculation your final modifier should be close to 1.5 at the maximum. These are the countries and their benefits: -- China Cheaper Infantry, based on the formula above -- Germany Cheaper Vehicles, based on the formula above -- Japan Cheaper Air units, based on the formula above -- United States Cheaper Sea units, based on the formula above -- Korea Cheaper Missiles, based on the formula above -- Russia Bonus land discovered, based on the formula above -- Dubai Cheaper buildings, based on the formula above |
