Year Start Sequence


 * 1) Calculate BRP base changes
 * 2) * May have increased due to mobilizations
 * 3) * May have decreased due to the following:
 * 4) ** For each point of Germany’s BRP base above 150, it must receive 2 BRPs from conquest of minor countries; any additional points in Germany’s BRP base are lost
 * 5) ** Japan loses 1 point to its BRP base for each air factor (or 3 NAS units) uninverted while under an air oil effect
 * 6) ** While loss of a Key Economic Area does not reduce a country’s BRP base, it does reduce its construction limit by the appropriate amount
 * 7) ** BRP deficits from the previous year (see below under BRP Base Growth)
 * 8) ** BRP base may not drop below 0
 * 9) BRP Base Growth: Part of the unspent BRPs from the previous year are carried over
 * 10) * Each major country takes the BRPs remaining from the previous year and multiplies the amount by its BRP growth rate percentage for that year; this amount is carried over to the next year, and the remainder is put towards Research Points
 * 11) ** BRP growth rate for unspent BRPs is reduced by 5% for each oil counter below maximum
 * 12) ** If there is a BRP deficit from the previous year, it is multiplied by the country’s BRP growth rate and the result is permanently deducted from the country’s BRP base; while the remainder is taken from the new year’s BRP totals
 * 13) BRP Totals: Other BRP income is calculated for a final total for the new year
 * 14) * BRP Gains
 * 15) ** Conquered major powers
 * 16) ** Captured key economic areas
 * 17) ** Colonies and conquered minor countries
 * 18) ** Minor countries that are allies, associated, or economically penetrated
 * 19) ** Captured or controlled ICs
 * 20) ** BRP Losses
 * 21) *** The remainder of BRP deficits from the previous year, after BRP base deductions
 * 22) *** Originally controlled Key Economic Areas controlled by another alliance faction
 * 23) **** Note that BRP gains/losses that occur during the player turns due to conquests, diplomacy, etc are prorated at different points of the YSS or player turns as indicated.
 * 24) ** Any BRP gains from Axis conquests in the previous Winter phase are received now
 * 25) Construction Limits: BRP points available for Unit Construction this turn
 * 26) * 1/3rd of BRP base, rounded down
 * 27) * -1 for every 3 BRPs lost to Transport shortages, Strategic Bombings, and enemy units adjacent to mapboard boxes
 * 28) ** Indian and Australian BRPs lost to Strategic Bombing lower Britain’s Construction Limit as well
 * 29) Allot DPs.
 * 30) * Basic Allotments:
 * 31) ** Germany, Britain, Russia: 3
 * 32) ** Italy, France: 2
 * 33) ** US: 1 per every 10 USAT levels.
 * 34) * 1 DP for every 100 BRPs (round down).
 * 35) * DPs from other sources: see the Diplomatic Tables.
 * 36) Allocate DPs
 * 37) * Each alliance faction may place up to one third of its DPs (round up) in any one target.
 * 38) * The Western Allies and European Axis may each place up to two DPs in USAT in 1939, and up to four DPs in 1940 and 1941.
 * 39) * The Western Allies and European Axis may each place up to two DPs in RGT in 1939, and up to four DPs in later years.
 * 40) * Russia may only place DPs in Bulgaria, Finland, Greece, Hungary, Rumania, Sweden, Turkey, the Ukraine and Yugoslavia.
 * 41) * DPs may be placed in intelligence research categories.
 * 42) Allot RPs
 * 43) * Basic Allotments: Germany: 8; Japan, Britain, Russia: 6; France: 3; Italy: 2; US: 1 per every 10 USAT+USJT levels.
 * 44) * RPs for BRPs: one for every 50 BRPs (round down).
 * 45) * RPs from growth: one for every 25 BRP lost due to BRP growth (round down).
 * 46) Allocate RPs.
 * 47) * No more than half (round up) of an alliance faction's RPs may be placed in a single research category.
 * 48) * Each alliance faction may only place 3 RPs in any given research or production project.
 * 49) * After having achieved 1 breakthrough in that category and if one country has 400 or more BRPs during the YSS, this limit rises to 4.
 * 50) * After having achieved 2 breakthroughs in that category and if one country has 500 or more BRPs during the YSS, this limit rises to 5, etc.
 * 51) * There are other restrictions for high technology projects, atomic research, date restrictions, and nationality restrictions.
 * 52) U.S. Election (1945 YSS only).
