# SteamEra Games of the Year Awards 2017

 [![Build status][Build image]][Build]

 [![Code coverage][Codecov image]][Codecov]

## Goal

To rank the best games of the year, a Bayesian Rating is computed [on RPGCodex](http://www.rpgcodex.net/content.php?id=10819), which provides a solid ranking. However, this methodology is not applied [on SteamGAF/ERA](https://www.resetera.com/threads/steamera-games-of-the-year-awards-2017.19342/), and a sum of scores is applied instead (think Eurovision). Our goal is to use the data shown on SteamGAF/ERA and re-rank games with other methods:

* a Bayesian Rating,

* [Schulze method](https://github.com/woctezuma/schulze-method)

## Bayesian Rating

### Prior for Bayesian Rating

Our prior is computed as follows:

* regarding the average score, the prior is the median of average scores,

* regarding the number of votes, the prior is the average of numbers of votes.

### Caveat

The original data consists in sets of GOTY candidates, which happen to be ranked. As pointed out by [Durante](https://www.resetera.com/posts/3904799/), interpreting the ranks as a score leads to undesirable properties.

### Result

Full result is [here](output/bayesian_ranking.txt).

## Schulze Method

### Ranked-choice voting

[Schulze method](https://en.wikipedia.org/wiki/Schulze_method) is an alternative to [Borda count](https://en.wikipedia.org/wiki/Borda_count), which is the Eurovision system. See [Ranked-choice voting](https://en.wikipedia.org/wiki/Ranked_voting).

### Data

The original dataset, which consists of the rankings submitted by each user, was used.

It cannot be shared for privacy concerns.

### Result
