As an alternate way to win a reset.
Each country starts with a number of general purpose resource points (GPRP). Each time a plane, vehicle or ship is destroyed or a base is taken, some GPRP are substracted from that country's GPRPs pool. Cities and factories generates GPRP slowly, and when a country reach 0 GPRP the war is won by the country with more GPRPs.
The GPRPs of each country may be shown in the strat panel.
The side effects:
A country with a lot of bases and players may need to be in deffensive due heavy losses with its players trying to keep alive as much time as possible instead of making suicidal strikes trying to take bases based only in major numbers.
A country with small numbers may be defeated much earlier(without the endless 3 last bases agony) if the attackers cause enough casualities.
A country with small numbers and no offensive capacity will always have the chance to defeat the bigger ones.
Some scenarios with big battles may be won in few hours instead spending entire days to take all the enemy bases.
