sory but i dont think any of the names is good..

[edarkdragon]

golden rash to similar to gold rash, the are more than one(or two) games with this name.
goldering it's little more original but i think you can be more creative then that (my lands it's really good)
other's name like Goldmach ,Goldmach war's, Gold to Kill ,Greed to the Death , Greedingring mach, can be more original
