Yeah, there is more than winning at stake(which does not excuse bad game design but eh), its more placing each character where they can make an impact on the scenario. This is problematic with party based games, where a default assumption is the whole party moves as one unit, and with combat based games, where the default conflict is martial in nature(and thus, the best way of killing things and not being killed, in that order, wins).
What you need to deal with power and focus discrepancy is breaking the one cardinal rule of GMing, Don't Split The Party. Divide them up by role and strengths, and place appropriate conflict therein. The problem again with that, is when you have multiple characters specialized in the same field, and a power gap is highly apparent.
White Wolf games do it slightly better in that regard. The starting premise of their supernatural lines are basically 'ok you're a Jedi, what sort?', so everyone is on the same starting supernatural footing. The 'expected' party(in quotes because few people actually run it straight like that), would have one character of each specialty archetype: Bruiser, Diplomat, Handyman(lore, tools, etc), Sneak and Special, and due to the basic game mechanic, competence gap grows slowly.
The problem of course, arises when you have games where one type of challenge becomes more common, most often in Bruising and Diplomacy, where you can have entire sessions based on them. Some fields are just harder to provide for than others.

"Just what do you think the moon up in the sky is? Everyone sees that big, round shiny thing and thinks there must be something round up there, right? That's just silly. The truth is much more awesome than that. You can almost never see the real Moon, and its appearance is death to humans. You can only see the Moon when it's reflected in things. And the things it reflects in, like water or glass, can all be broken, right? Since the moon you see in the sky is just being reflected in the heavens, if you tear open the heavens it's easy to break it~"
