Hull, I have a small idea of a game members and urself could work on-
Like a card game, you collect cards and battle with them, like the old pokemon cards back in the day. Members could trade and on your profile could say how many cards you have, mabye you start off with 3 random cards, then when you battle you submit a card and if you lose the card goes to the winner. Also there could be rare cards were admins can give out, or shinys.-
