I have another request/suggestion
If anyone wants to take it on it might be nice to add in a token system or to use ucash in order to have people pay to play each game and recieve tokens for winning.
Something like an option in the admin part to turn on the use of tokens, then something for each game where you could put how many tokens the game cost to play.
Then for winning you could do some random numbered token reward based on total tokens stored for that game. You could even go as far as listing how many total tokens are available to win in each game's info window in the arcade.
Something similar to what what
