I like Jest's idea
for this approach...
...but in fact, I doubt "removing" games from games you know is really relevant.
Shouldn't we
fix how the data is used, rather than trying to reforge actual facts ?
IMO, what is relevant is removing games you want to ignore
from places where you don't want to see them.
The functionnality could easily be "hidden" somewhere in the profile or in a submenu, and games could have different statuses, like "Ignored", "Appreciated", "Favorite"
So, what are those places ?
• Game list ? Indeed, hiding games you want to ignore could help browsing games.
• Game history/stats ? IMO, removing them here is irrelevant. Maybe hiding them by default, to lighten the display, but keep a punctual "Display all" button
• Specific games forums => Just hide unwanted games the same way "not known" ones are
Any other place ? And
why is this display an annoyance ?
Btw, I would love such functionnality.
