IMO, sometimes yes. It depends on the question.
Reason is, Question title have a limited length. Also longer titles are hard to read and discourage people to read it at all. Also a title (according to only the title itself) may refer to many different systems/campaigns etc. A question about spell casting might be a too broad category, and title might not be able to define the whote idea by itself alone. In this point, tags are very helpful.
In a page with 50 questions (some of which are highlighted) is quite crowded, long titles discourage me to read the question if it is too long. So, I prefer to check the tags first before I examine the question title. Reading broad-topiced question titles before the tags may lead me re-read the title again after I examine the tags to evaluate the question more accurately before I decided to click it and start reading the question itself.
So in most cases, tags are as important as the title for leading the reader.
If question is a comparison/simulation question (as it read from the title of the question), then people will check the tags to see if they are interested. If I do not know both of the related systems, then I would not consider reading the question. If I know or have any idea about one (or two) of them, then I decide to read it.
