Is it OK to ask for information about an upcoming game?
When is Halo 4 coming out?
Or is this too speculative/subjective?
The problem with speculation questions is that they're often on the border of closing.
Prior to the release date, it's subjective because it's only when people expect it to come out, you can't get the factual answer until release.
Post release date, it's too localized because it's no longer relevant.
However, if it's not something that's going to need speculation (i.e. there's a strict release date and people have even started pre-ordering the game), then there is a strict answer and it is a valid question, so it doesn't need to be closed.
I think they can be more trouble than they are worth, but if we can actually answer them, we shouldn't spare it a second thought. So make your judgment on a case-by-case basis, not as a whole. I would prioritize answering these whenever it is actually possible, and vote to close when it's going to just be speculation.
I do not like these type of questions because I cannot see the added value for a site like this.
A lot of times this question could not be answered even by the developers/publisher. Look at Valve Time, for example.
I disagree that such questions are useless after the release date. Instead, it makes sense to reword them from "When will game X come out?" to "When did game X come out?"
I think that games that do have a set release date should not be closed, unless it is decided that they are off-topic. Then they should be closed for that reason, not for being "too localized."
Games that do not have a fixed release date, or so-called "speculation questions" do not fall on the border of being closed for me. I think a question very much deserves to be closed if we know that nobody on this site can provide a correct answer. They can be reopened when that is no longer the case.
The close reason given should be "not a real question" because they fall under the category of "This question ... cannot be reasonably answered in its current form."
I don't think any release date questions should be closed. It's useful to know the anticipated release date even if it turns out to be incorrect. We of course don't want to retain stale information, so to update outdated release questions we'd need to maintain a list of them on meta. Once the game is released we can change their tense and drop them from the list on meta.
I really think the focus of this site should be about providing users with accurate and helpful information and not searching for reasons to exercise community moderator power. I have more thoughts about this, but that's for another topic.
If this suggestion gains traction I'd be happy to post the framework of the meta list.
