I am looking for a Multiplayer, interactive online sports game. Perfer Baseball, Football, Hockey. Game to be used for Charity, need ability to place "ads" in the game, 3D type game with scoreboards. Want Chat/messaging so players can chat with each others. Players would have to have ticket number to play the game. The game will be used to raise money for children's equipment such as wheelchairs, speech communication devices, braces and so on.
