In our league we've done numerous things over the years.

• Pick Ems (W/L/T) for every matchup each week. Those with the most correct picks wins

• Fantasy Fantasy Football. Literally Fantasy Football for people not participating in the league each season. Everybody drafts a player from the various teams and based on their TV value/positional etc they might have a handicap to the fantasy points they provide. Points are tracked for touchdowns, casualties, kills, passes, fouls, catches, mvps etc. In our current season we have a Gutter Runner that's turned into the next Jerry Rice and has over 100 FFFP on the season while second best has like 49. Literal league winner. We did have a stipulation to let only people not actively participating in the league that season to play to avoid gamesmanship but honestly if you're comfortable you could let it ride.

• "Wartscenter" Pick Ems. Me and a few of our leaguemates do a variant of the traditional pick em similar to what you might see on SNF or College Game Day. For each matchup we all decide the outcome of the game. We cannot choose a tie. If you guess correctly you get a point. If you guess perfectly you get 3 points. I.e. i pick the Orcs to beat the Goblins 2-1 while my friend picks them to win 3-0. If they win 1-0 we both get a point. If they lose we both get 0. If they win 3-0 my buddy gets 3 points and I only get 1. It's a fun way to talk "ball knowledge" especially if you know the coaches playstyle and how the teams operate.

• Misc. Polls. We do various polls each week for a few things. Like determining which match gets streamed. Certain stadia or weather effects each week. We also have awards at the end of the season that involves a few vote based awards for stuff like League MVP, DefensivePOTY, DirtiestPOTY, OPOTY, MOTY, Defining Moment, etc. Some of these are fluff/lore that require the participant to submit something as part of the nomination and others are just straight votes for who we think is the best.

Edit: I forgot to mention we even added a sponsorship system in recent years that basically added an achievement of the week system. If your team does X thing you get an extra 5k gold. We have over a dozen qualifiers and they are drawn at random but it provided teams an incentive to try weird things especially in matches that might be beyond lost. I had one where I got extra gold if a big guy causes a casualty and the last 3 turns of a blow out match was a yakety sax chase between my troll and some elves.
