Sadly very few games focus on non combat conflict. I think AD&D birthright, and legend of the five rings do a good job bringing politics and social courtly behavoir into the game. Call of Cthulhu brings the whole you can't win conflict. Most games however, combat is the central theme, which is too bad, because with the right amount of creativity there's all sorts of non combat conflicts you can create. The problem is, that all other conflicts tend to take more story elements to craft, while combat doesn't even need context or backstory, you just throw orcs out and say "fight". I think because it's so easy, it creates lazy GMs that the industry caters to.
You're right, combat-driven scenarios are easy to design (and therefore fast & cheap to develop) so it's in the industry's best interests for gamers to remain content with the "Kill X, find a clue, then Kill Y" formula. And in most cases, gamers are happy to oblige.
