Right, I knew of card games (Bridge for example, but there are many others) that used such points systems, but we couldn't think of a board game before Outpost.
I think the distinction I'm trying to make might be overly fine, though. Really what I'm looking for is the oldest game that used "points" to compare things that wouldn't be comparable otherwise. In mancala, ultimately you're comparing how many stones you've captured, right? (Honest question, I'm not 100% on the rules of mancala.) In Catan, settlements, cities, longest road, largest army, and some of the development cards all "count towards victory", but they don't count equally, so you need some valuation system to quantify them.
