I'm sure this has probably been suggested a few times through out the past... But just in case it has not;
How about a custom Black Jack / Texas Holdem / Slot machine mini game to help people earn FG?
We could have tables / rooms very from .01 Max bet on FG to 1 / 5 max bet on FG. (ie. Room 1 (min/max .01/.1) Room 2 (min/max .2/.5) Room 3 (min/max 1/5) Or something. Or even just slots with a .01 - .02 - .05 - .1 bet you can place on each spin.
Just thought something like this would be a lot more fun that ladder slasher, and something that is doable that can help people earn FG in other ways.
