How about rewarding players with different dice, that they could then customize into their own games, allowing their dice rolls to show the dice they want.
- We could provide different dice for such things as:
Anniversary of membership.
Reaching win totals of... 100, 500, 1000, etc.
Reaching completed game totals of, 100, 500, etc.
Rank dice awarded when they reach a rank. (They would keep it even if they dropped below), but it serves to show they reached it.
and so on...
How this will benefit the site and/or other comments:
This would allow players to customize their settings even further.
I know this would mean some kind of coding needing to be done to allow such a setup, but I think it might draw more players in the long run.
