This is in fact an old idea. It muust have been lost with the old forums or simply it was never mentioned in public.
The idea in general includes a number of available facilities/upgrades (or simply named as wonders) which will be available to the gangs. They will be purchased for a standard sum which will double every time one wonder is purchased. Up to 3 wonders perhaps will be the maximum selection.
Now, some common examples could be 10% more cash from crimes or 10% more xp or 10% specialization boost, or 10-20% cost deduction in upgrading secondary statitics etc. There could be wonder also affecting rob another player features or mob costs-cuts etc. We can also have wonders that are needed for specific industries.
I know some may find the idea bad for solo players but the game is intended to be multiplayer. We might create a solo server some time afterwards for those that want to go solo. Before this can happen, the rob another player feature will need to be perfected.
Finally, you need to know that gang wonders are integral part of the game future (you must have noticed an open space in the table in manage gang. This was destined for the gang wonders as they would be released alongside with the full game but there was simply not enough time.
You may suggest type of wonders. Here is a full way to do it in a nice, structured way:
Wonder name: Cash Laundry Network
Building Costs: 250 Millions $
Building Item Needs: Nothing (Or perhaps a basketball or football team ?
Daily update cost: 50.000$
Affect: +10% Cash from every crime each gang member does.
Cash Laundry network is in fact a series of paid person who work together in order to cover the "dirty" money generated from illegal activity. It costs a lot to find the right persons, setup the needed legal enterprises and buy whatever other buildings needed. Also, money for its construction are spent to find the right persons to do the job while also some are spent for the right briberies to the right persons. The cleared cash generated from the whole business is a lot but since the whole system needs much in order to function, the final earnings are around 10% of the initial ammount. Finally there is a daily update cost of $50 000 as these are used to cover the clear steady costs such as rents of the buildings. The people working on it are getting paid through the dirty money so this is not an issue for you.
Way to go then. The more choices, the better. Also, this can be a good way to spend the gang money.
