As a roblox player, it is hard to tell the quality of a game based on the like/dislike ratio. There is no way to tell if a good game was just dislike-botted, or if a game truly is garbage.
Currently, we only can see the global likes/dislikes for a game.
A possible solution would be to show a graph of the percentage of likes over the past 2 months when hovering over the Like/Dislike bar. The Y-Axis would be the Liked Percentage (e.g. 73% liked), and the X-Axis would be time (in weeks over the past 2 months).
For example, if there is a large dip over a week or shorter, you would be able to know if a game was just botted. If a game has a mild decline in Like Percentage over time, you know that the game is not worth it.
In conclusion, this feature would help players judge if a game is truly acceptable to play.
