Something I did was create a list on How Long to Beat of games I don’t want to play, sort by most popular, and filter out those games and ones in your Want to Play list too. It’s not really recommendations at all but it was a good way to look at new games you havent seen before. In terms of getting recommendations, finding a YouTuber with similar taste in games as you could be a good way to do it.
It does, but as far as I know PD3 still requires an online connection for single player. I’ve read issues of people lagging in single player, that’s crazy.
