How does sp works ?

The reason i ask is because i usually pick china and when someone else pick china as well. we usually have a duel and sometime i come out the winner and have 200 plus sp but when euro countries ally each other. i ally with india and fight them but somehow i always take half of there land and still am the 2nd to last on the sp at the end of the game

So you gain sp in games from killing units or taking cities and even more if you kill someone. At the end of the game if you lose you get half the total sp you earned in the game. So if you die or surrender and you had 150 sp, you get 75 of it. If you win you get all of your sp plus the sp of other players hwo have died or surendered divided by the total number of allies you have. For example

You: You have 3 allies and the game ends and you have earned 500 sp
Alyy1: Has 400sp
Ally2: 300sp
Ally3: 200sp
Other player1: 100sp
Other player2: 150sp
Other player3: 350sp
Other player4: 300sp

Here is what you earn:
You: 400+ (900/4 = 225) = 625sp for you. Where does the 900/4 come from? The other players who lost have a total of 900sp. SInce you have 3 allies the 900 is split 4 ways (You and your 3 allies)
Now say it is the same scenario, BUT other player1 abandoned the game instead of dying or surrendering here is what happens:
Alyy1: Has 400sp
Ally2: 300sp
Ally3: 200sp
Other player1: 100sp (Abandons game)
Other player2: 150sp
Other player3: 350sp
Other player4: 300sp
Here is what you earn now:

You: 400+ (800/4= 200)= 600sp for you. In this case it is only 800 split between you and your allies because when someone abandons the game they don't get any sp nor does there sp get calculated in for anyone else.

Hope this makes sense let me know if you have any more questions

Ahhhh no wonder thanks most people abandon the game

Anytime ^_^
