user7579: Recent examples are https://anime.stackexchange.com/questions/34353/rezero-kara-hajimeru-isekai-seikatsu, In the Erased manga do Satoru and Airi get together?, and Does Ash walk away from the starting pokemon in the anime?. 
The common thread among these questions is that the OP is familiar with one form of a story (the anime, the game) and is asking questions about what happened in some other version (the manga, the anime) which are obvious to someone who's actually read/watched that other version.
We seem to be entering a bit of a close/reopen war on these. I keep going back and forth; in my opinion, they're not good questions, but I'm also not sure they should be closed. Downvoted, yes, but I don't know about closing.
Anyone have an opinion on this? Should we allow these in general? Should there be any criteria to decide which ones are too silly to allow?

Should we allow these in general? Should there be any criteria to decide which ones are too silly to allow?

I think there should be some quality threshold to avoid having to answer and keep questions like this one. For example, if answer can be found on:

Wikipedia or anime database page for the work;
First page of a google search (somebody already asked this on forums or answered in reviews);
The thing in question is made pretty obvious at the beginning or the end (which are both easy to locate), except where that something is implied and you think some viewers could miss it (which is probably evidence they didn't pay enough attention, and so they're being lazy by asking such a question).

If answer can't be found like that, I think it's reasonable to say it's not easy to find it, and it deserves a place on the site.

user191: Re zero is just too silly to even consider as a valid question, so let's not mix it in together with the other two.

Regarding Erased question…
There are cases where you can get an answer relatively easily, like (in my opinion) in case of this Erased question, by just browsing the manga's last pages and seeing how it diverges from anime. But these are just 2 versions, so as I see it, OP didn't bother to look it up, and so I downvoted the question for lack of research. 
And then there are not so easy to answer questions like works with multiple continuities, different twists on the same story, alternative setting, etc. For example, Ghost in the Shell which has many movies and series.
I don't think it should stay closed, as it's a valid, even if not a very good question of its kind.

Regarding Pokemon question…
OP says:

I've not seen the show, but I used to play the video games.

It is not stated which games, but I've played Yellow and you just don't get the pokemon you were supposed to get because your rival is mean, and it's within the first few minutes. But I assume that OP wasn't playing Yellow, and the newer games do give you some choice of a starter pokemon (haven't played any myself).
But that's not why it was closed. Because it was put in a way that it asks about the Pokemon Go game, it's not on topic here. The answer was given to a very related, but not the same question. I think we can fix this case by editing the question to "How does Ash get Pikachu in the anime?" and then it would be on topic.
update: I edited the Pokemon question to be on topic.
