HI! I have started a new gaming tournament! the winner of each tourney can win a 2000 DSi point card or a greater prize! Don't worry I will send you your prize via mail or if you want I can email you the dsi points card code. During matches I shall be spectating the player as they battle/or what evz. In the future admins may be assigned to spectate when several matches occur. Or when I just can't be there :P. for now the main games will be mkds or metroid prime hunters. I can get any game though because I have an acekard2i.
