Cost for Wonders? Negative cost?

[Ecce Homo]

Has anybody managed to make Wonders cost gold for maintenance? I tried to give some Wonders negative cost, so that they would give a revenue, but that didn't work.

Any ideas?

I can't do it just via rules.txt, but if you have ToT, you can try:

@IF
ImprovementBuilt
Improvement=whatever number it is
@THEN
GiveTechnology
Technology=Whatever tech you want to use
@ENDIF

@IF
RecievedTechnology
Technology=Same as above
@THEN
CHANGEMONEY
amount=however much money you want the wonder to generate.
@ENDIF

To add a maintainance cost to the wonder, just set the cost to any positive amount.
