For a fantasy sports draft app, I'm trying to design a voting system where winners receive trophies in categories like "most lopsided trade", "best overall draft" and "best draft steal". The voters would be the participants themselves, typically between 10 and 30 in total.
The voting period would ideally take place after the drafting is finished, and the user would be guided through a screen for each category to be voted upon during a specific time limit (perhaps a minute or so).
The main issue is the sheer number of (very subjective) detailed options to vote upon (tens or hundreds of trades involving multiple players of differing values and salaries). To combat this, I'm thinking of a two-stage process (per category). The first stage would be a simple (low mental effort) list of ~5 options that the user ticks yes/no to. Each option would be presented to at least ~3 users in aggregate, and the options with the lowest votes would be discarded. The second stage would present the remaining options in more detail, and the user would rank their top 5 picks (1st gets 5 points, 5th gets 1 point), and the option with the highest points wins that category.
How should I encourage users to complete the full voting process?
I've been thinking of either an additional trophy awarded for full participation, or some way to make the user's own trades more prominent during the voting process the more often she votes.
Am I on the right track here? Or are there any other systems like this in existence that I could draw some inspiration from?
