I'd like to see how good iam after beat the game. So the idea is:
Like the other games that have leaderboard, after u beat the game, the game will ask you to save your game, or autosaved if u play ironman. Then that save file will display your specific score + overall score + Top 10 best soldier (+ how many they kill aliens/teammates/civilians + what equipments they used + stats) + memorial + what difficulty are u played and display all the bases.
So players can compete each other and show off their score.
