Certainly I think asking for a game-recommendation is bad (not just for the asker but the site in general).
Now I know at least one other question was fine based on the fact that the correct answer is: there really is only one (actually two now). I'd like to discourage people trying to squeeze game recommendations in by saying: I've narrowed it down so there is only one answer, as that only introduces a flood of questions of this type, and really those questions are just as bad as any other game rec (ie. little more than opinions).
In your case you asked for "Is there any other turn-based-strategy game on the Wii?" and the reality is there are 100s. But even if you narrowed the question down further to something like "Are there any other turn-based-strategy games on the Wii where you build an empire and research technologies to advance the units you can produce?" I don't really think that's any better of a question.
At the end of the day you want a recommendation for a game to play, and recommendations are just opinions. Whether or not you enjoy the recommendation is also an opinion. No one else could pick a correct answer for that question besides you, even if they had access to your set up.
Its too personal.
Edit: for clarity here is the question we did decide was ok. While still borderline, the question was ultimately "does the map making capabilities exist on the 360," and the real answer there is that "Not explicitly, but a game maker could put them in."
