Can you point me to a StackExchange site where I can ask "What are some good action RPGs like Mass Effect or Deus Ex which you have enjoyed?". In fact, I discovered and joined Quora when a very similar question of mine was deleted from gaming.SE.
In Quora, for most questions, I AM looking for opinion, not factual answers.
Arqade (Gaming Stack Exchange) doesn't allow game recommendation questions. In general, such recommendation questions are not a good fit for SE, some sites allow them but many don't.
Some people just ask those in chat, which works reasonably well, but you need 20 reputation to do that.
