I understand adding certain updates will require a longer turn time but what ever. Also I understand this is alot. @Alex
Currently the game is veeeeeeeeeeeeeery boring with it being as repetitive of Sea of Thieves. It has come to the most fun thing is to raid ppl.
~ Add other sports like Football (Merica), Football, Lacrosse, basket ball (these should earn you more money as i see no point investing over 1 million when it will take you nonstop all day 24/7 to keep on hitting that baseball game button. To me its a waste of time and money.
~ Add more customization to the armed forces. (this can be for VIP) Be able to make divisions and name tanks. (they wouldn't affect warfare but they would add more customization to nations). Example ~ Can assign an amount of soldiers to Marine corps (cannot bypass current amount of soldiers) This would be same for tanks, you can assign a current amount to be light tanks or heavy and name them. Same with planes and Ships. You can have Aircraft carriers.
~ Projects: Dockyards (would allow you to build Aircraft carriers and Battleships.)
~ Military points - instead of the current system, you can have points instead of exact value. u already kinda have this but lets say you make a destroyer, It would only count to 1 point to your navy. If you were to have a BS (Battleships) It would count as 2-3, AC (Aircraft Carriers) will have 3-4. Same for tanks.
~ Planes- you would be able to make strategic bombers ( they would damage infra and improvements heavily but cannot operate without air superiority.) Fighters (Self Explanatory, they will fight for air superiority.)
~ How are you going to make hangars without an airfield? Add an airfield as a improvement for a city (will cost resources) But then you can build hangars, (which will cost resources and money but very little.)
~ ^ this bring me to another topic. Mini projects - you can make mini projects in each city, they would cost alot but be very beneficial. You can make a Airfield (and create hangars) You can make a civilian airport (which will bring in tourists) Also airfields would only allow up to 5 hangars but an airfield would come with like a holding capacity of 120 planes.
~ Speaking of tourists, they would count as another source of income. In the project menu you can build a certain world wonder which will increase your tourism and therefore increase income. (they would cost alot to build tho and an okay amount to maintain.)
~also add land calculator
