A number of replies to that thread had lists of 10+ game titles with absolutely no info on any of the games mentioned

Two. There were 2 people who posted more then 3 games in a list without more details about the games. And after going though the first 3 pages of the sub I found one other post with more than 3 games listed that didn't have additional details about the game.

This is a non-issue that affects very few people negatively (and seriously are you negatively affected having to see a non-descriptive list) while simply pushing users away or causing an already low activity sub to have even less posting activity.

If you don't like it hide it. Down vote it. Respond to the person with the games in their list that you do like and include more details.

Oh, and you know what is even more useless than these non-descriptive games lists? People replying to these list comments complaining about how their list isn't useful. Because that response was so much more useful than the list.
