It already gives everyone a fair chance. That's like saying people who get a lot of credits from fireworks or pirates should be cut off. It's just like falling chairs, first person to click the spot gets it.
This one game, while I like is giving the economy credits at the moment, has a set system that I believe should be limited to something along the lines Jedi said. Maybe something like 15k every 12 hours. I don't know. I don't like the idea of this game being based mainly on two rooms. I personally like relizabeth's suggestion for this one about it being all the same.
Again this game has been very good and I support it but I feel like I'm having a harder time making credits than beating the Four Kings by myself in Dark Souls on New Game. (Yes I made a video game reference with a video game reference and I know only some will understand this.)
