Not sure if this has been done before and failed horribly but could some sort of HUKD gaming league work?
Where we sort of team up in groups of 5/6 and play multiplayer. A league of sort where each teams result is recorded.
Perhaps a weekly game with points for winning or drawing(??)
Game could be rotated to the most populated team multiplayer title at that time. Titanfall 2, a COD or Overwatch spring to mind
Just gauging interest to see if it would be worth or possible to do
