As a Roblox developer and as a Roblox player, it is currently impossible to view the games that I have liked in the past. This creates a problem as, the user wants to be able to view good games, and we assume the user likes good games in their opinion. It would be a good user experience to view all of the games they liked.
There already exists a game sort for “Because you liked”, a game sort on “You liked” is the next logical step.
If Roblox is able to address this issue, it would improve the experience of users who like games, and could improve game communities and loyalty as there would be another sort to quickly access the games players like.
