Should questions asking us to describe a game be closed, and if so, why?
No
In this case, the answer was easily found so beyond providing an answer the only other suitable action would be to down vote for lack of effort.
There may be cases in the future where you know a game by title, but cannot find any details about the game. Asking for a description of such a game would be appropriate for the site.
Minor Update
The OP clearly wants the question closed anyway, so no need to vote to re-open.
However, Robotnik raises a good point:
...it really isn't up to the OP whether the question is closed or not. They can vote, however ultimately questions and answers here are 'owned' by Stack Exchange - if we wanted to keep it around it is within our power to do so. The OP can request to be disassociated with it entirely, in which case they won't earn/lose rep on it. Its a bit moot in this case, I'm just pointing it out because people might get the wrong idea that requesting closure may not work if the community deems it worthwhile to keep.
