I'm using this mod a lot, in all of my game because the pace is just right and it allows you to create a lot of units and make these huge wars.

Unit cost only cash to maintain during the main part of the game, but at the end they also cost ressource (oil, coal). Since you also need those ressources to power factories, you're always short because the game didn't intend you to have so many units.

I think the mod should also increase the amount of strategic ressources you get at the end, wich only apply for coal, oil, alluminum and uranium.
