For now all it can be used for is if you go on a trip to prevent timing out in your games.
We have written down some ideas for gold features from the other forum thread that we plan to do but most of them will be for any gold member. One thing you suggested is the ability to bet credits in games which is on our todo. That could be fun.
I also thought about a credits ladder
, not sure if people want to show that public.
I know many games have the ability to buy in game advantages but that works better in MMO games where there are so many other players that you can't dominate the entire game no matter how much you spend.
But any ideas are welcome, for us it's a chance to make a bit more from people who can and want to buy extra things.
One thing that I have thought about is along the lines of poker where you bet money, or buy in to tournaments where the winner get the credits and you can withdraw credits to cash. Of course this would be a big undertaking but and it would probably have to be something else than the current credits since we can't afford giving new players and winners of the ladder cash the way we do with credits. The question here is more if this could be something at some point to go after.
