Popularity of 'MMO' over time
This chart shows the amount of games released over the years with the MMO feature and the percentage of games released on Steam they account for. The number of releases gives a sense of the amount of games published each year. It often increases, following the total amount of Steam games released.
The percentage, on the other hand, gives a better idea of the trend a feature follows. It shows if, in proportion, the MMO feature is getting more or less popular from a developer's perspective. The Review chart can let us know if this trend is a positive thing (i.e. players interest for the feature is growing) or a negative one (the feature is overcrowded).
The MMO game feature peaked in 2022 with 186 games released. The popularity of the feature is in a range between 0.21% in 2010 and 0.89% in 2012.
Keep in mind that the current year is not over, so the number of games released will still increase. But the percentage is usually a good estimate.
Evolution of 'MMO' game reviews
This chart shows the reviews for games with the MMO feature, either as count and as a percentage of all Steam reviews, and the average value for a game. If the normalized and average lines are too small, you can deactivate the review count and % of the average lines by clicking on the legend.
The review count gives a view of the sheer amount of reviews a feature receives, but it also follows the popularity of Steam itself. That is why the normalized value as a percentage of all Steam reviews is often more interesting, as it gives you the popularity trend for MMO feature games.
A typical game associated with this feature collected on average between 18 (2010) and 3231 (2014) reviews. Keep in mind that it is the average and not the median, meaning it is heavily influenced by extreme values, like a very successful game with this feature.
The reviews per game as a percentage of the average show that games in the MMO feature received between 49% (2010) and 545% (2015) reviews compared to other features.
