I came out of the woodwork as (GM person) approached us a couple years ago asking for MMO tech, coding and modelling services.
For our MMO tech, we use similar what Age of Conan uses.
When the Greed Monger guy came to us, he wanted everything for free, or the contract was so worded that we would get a fraction of what should be the value of the services rendered.
Coding - for royalty while demanding AAA quality.
Modelling - high quality for free.
Due to our friends' feedback, we didn't deal with Greed Monger person and stayed away from him.
One of the persons on Greed Monger - KS page - Steven Davis - is a known scam artist:

The legal contract was so worded that if we signed it, we would be sued for NDA breach (considering what a PR nightmare GM is), our code and models would be used for free without any payment until GM makes money, after game starts, excluding all pledges, gifts, pledges and KS money.
The estimated sum is more than US$90,000 as on KS page. The private donations run twice as much. More like a total of US$200,000 as the private pledges were equal that of on KS page.
A few weeks later, one of the modelers I know, had it and posted this, then (GM Guy) threatened to sue him

JamesP, you have my sympathies. You shouldn't be doing coding projects for a pittance.
