The question is asking what language to use for small, in-browser games, such as tower-defense games, RPGs, and multi-user dungeons. The OP was told somewhere online that ASP.Net MVC would be suited for this, however is (rightfully) questioning that answer since it doesn't seem right.
I think the question, in it's current form, is a decent one for this site and should not be closed. The only suggestion I would really make is to write out the example game types because not everyone knows what muds, tds, and roguelikes
are.
I do not think this is too broad of a question since the answer the OP seems to be looking for is to use an RIA technology. Which one to use is up to her. I also don't think it should be edited to include a specific example because it would limit the question to only being useful to the OP, and not to any programmer wishing to build small browser games.
