Developer Gold
 

I am not familiar with this yet so I have a question, Does this also provide Gold Subscription? Because what I can only see on the description is "Server Renting".

It only provides gold for your server. So, no.

I think it's a rip off, especially if your game is unsuccessful. The price should be low and then go up as your profits increase.

Profits? I did not know that anyone actually made money off of owning, managing, or successfully running a server.

Yeah. Unless they wanted to pay someone and Unixmad would release his hydraulic grip on Stefan's wallet, you won't see a dime come out of a server and into your pocket in you life.

you wont have the trial mode for you on your server. so basicly you are a gold-subscription player on your own server. but i dont think that this kind of gold-subscription will also count for other servers - didnt buy my own server, so im not sure but i think i heard stuff like this

Basically, you'll be given a server upon purchasing Developer Gold, and not only will you be able to access RC on that server, you will not experience observer mode and other trial account limitations on it either.
