There are definitely historical artifacts floating around that would probably be closed quickly today. I go through more or less monthly and delete some old closed questions, and then close some old list questions so they will all eventually be addressed. It's not a fun task, I don't particularly enjoy it; instead I focus on ensuring that new questions are of sufficient quality.
If you wish to speed the process, feel free to flag them, this will "force" a decision quicker.
In terms of what is acceptable, please see the FAQ. There is a lot of good info there as well as links to some worthwhile blog posts that set out to explain the "StackExchange Way".
Two reasons that most list questions get closed is that every answer is equally valid or that you could imagine a book being required to fully answer the question.
Subjective questions are allowed. (This seems to be a common misconception)
The definitive guidance is the blog post Good Subjective, Bad Subjective. A list question would have to be very carefully worded to avoid the six pitfalls listed there. In particular:
- Great subjective questions inspire answers that explain “why” and “how”
- Great subjective questions tend to have long, not short, answers.
We do not want questions that lead to an endless list of just game names. That is not interesting, people will be voting for the game and not for the best answer. Back when we had many more list questions it got to be a race to be the first person to mention Dominion as you could rack up quite a bit of rep. Is Dominion the best game for all occasions or is it more likely that it is a very popular accessible game that everyone knows?
