About Gems, Upgrades, etc.

[MaharajaInfernape]

I have a quite large idea.

• Completing a map giving only 4 gems in maximum and needing so low amount of gems to purchase a unit/upgrade do not look good. I suggest that there after all the gems are refunded, as said by godOfKings, they will be multiplied by 20. The costs of the units will also be increased.
• Completing maps in hard campaigns will give more gems than completing maps in medium or easy campaigns.
• Completing a level will give some gems. The amount shall increase on reaching higher levels. (I would write fully completing a campaign should give some prize but I didn't because new maps are often added in new versions.) Similarly completing an achievement will also give some prize.
• There shall be 2 types of currencies—one gems and another diamonds. Diamonds cannot be got easily. Some units will need diamonds or both gems and diamonds to be bought. Also, 1 diamond can be converted to 20 gems or so but gems cannot be converted to diamonds. Diamonds can be sent from one Ao game to another.
• Similar as said before, some units/upgrades will need the player to reach certain level or/and have certain amount of stars to be bought.

This suggestion can be applied to AoD.
