Didn't CtP have something along those lines Valkrionn?
To me it's become clear that Civ is just the wrong game to have 1UPT.
Civ just has the wrong scope.
Besides, 1UPT was the solution to a problem that doesn't exist.
Well, of course it DOES exist, but only for truly hardocre gamers. The problem only affects those that play on the highest difficulties and who are thus subject to incoming AI SoDs or those who like to game the system by bringing their own SoDs to unexpecting AIs.
I VASTLY preferred Civ2's approach - you can stack as many units as you like, but if - on the defensive - ONE of your units is defeated, the entire stack bids farewell (unless it's in a fortress). This meant there was a natural incentive not to overuse the benefits of a unit stack.
Always damaging other units in the tile and/or forcing them to retreat (and disbanding them if there's nowhere to run) would be another solution.
About units decreasing performance the more crowded a tile is ... I'm not too fond of it. If there was an army mechanic, it'd be feasible to have the strongest army on the tile fight the battle, with the army's own reserve units AND any additional units on the tile forming the reserve, but with a limited capacity to bring reserves to the field and a limited "frontage". Kinda like in AGEOD's wargames, if anybody knows them.
1UPT is much better if the scope is different and units that have a movement range of, say 5 can be considered slow. In Civ, though, even a unit with movement range 2 (not including the additional bunny-hopping movement point every unit gets in Civ5) must be considered fast, at least for a long time.
But wait, why is this discussed in a thread about civ5 modding being dead?
On THAT topic, I have a question: In the Warhammer mod discussion thread the screenies feature imported WH2k units. Is it now possible to import unit art using the official tools (or some other means)? How about building art? Any news?
The people in that thread refuse to answer that question ,for some reason, and looking at the unit graphics subforum, it's still not exactly a hub of activity...
