Ok, well this will be fairly on par with what this is... Hockey Themed Dungeons and Dragons!!!
You could do this with 1GM and 2 players (head vs head) where each controls a small party or "team". It will be made up of unique positions such as "Offensive Attacker", "Defensive Specialist", "Floppy Goalie", "Fighty Angry Man" (Actually, this might just be barbarian, replace their weapon with a stick). So in the small 3 player game version we have 1 GM, and each player will have a team of players where they have to turn based maneuver against each other.
This can scale up to a 4 player game with pre-made obstacles. You have 1 GM, 1 player controlling the forwards, one controlling the defense, and one controlling goalie. You would have challenges such as digging the puck out of the corner, making a laser 50 foot pass through the other team, scoring on the resulting breakaway - hopefully you don't roll a 1 like McDavid did last night.

An additional ramped up version includes 7 players, either coop or head to head. Head to Head is 3 on 3 as explained above, with 1 GM and you are going against the other team using your pure mental superiority. The other version is like the coop 4 person version, except you have each player control a specific player on the ice, working through pre written challenges. We can also publish some official ones and include tips for some money for our sweet sweet DDoS protection.
The ultimate version of this is played with 13 players. That's right, 1 GM, 6 players per side. Full on blood bath.
Pizza is served, bring your dice, character sheet and a pencil.

I'd like to play this version, here are my proposed teams:

Team Winners
@CementHands
@slothfacekilla
@charlieconway
@Rublic
@Flareon
@BadWolf


Team Ice Dawgs
@Citizen of Adraa
@TheDangaZone
@sailingdrumstick
@mxman991
@JR95
@notoriousTRON

And the GM for our campaign will be none other than Wil Wheaton.
PS. I believe this has the added benefit of pretty good balance. Say you load your team up with "Sniper" type characters. They are going to suck at a lot of the challenges, so maybe don't build a team around that :eyes:
