Civilization Revolution (original) — Combat & core mechanics (raw capture)

Game: Sid Meier’s Civilization Revolution (2008), the ORIGINAL. Sources (Tier-1, community): CivFanatics CivRev Info Center + Fandom/StrategyWiki, via WebSearch summary on 2026-06-22 (GameFAQs HeroicHylian guide and StrategyWiki return 403 to direct fetch). The MODIFIER STRUCTURE below is well-attested; the exact per-round win-probability is NOT documented (it’s the hidden part → measure on live CivRev2, with the caveat that CivRev2 may differ).

Combat — modifier structure (grounded)

• Each side’s strength = base Attack (attacker) vs base Defense (defender), then modified.
• Veteran/Elite: a non-veteran upgraded to Veteran = +50% combat; a Veteran upgraded to Elite = +1 Special Ability. (Barracks/Great Leader produce Veterans directly.)
• Stacking rule: all percentage bonuses are summed first, then applied to the base; then absolute bonuses are added after. (So veteran +50%, terrain +50%, fortify +50%, walls +100% add into one percentage multiplier.)
• Fortify: ordering Defend = +50% defense; left defending → Heavily Fortified = +100%.
• Terrain defense: Forest +50%, Hills +50% (Hills ALSO grant an offensive bonus); Walls +100%.
• Auto-resolve shortcut: battles at 7:1 odds or greater are automatically won.
• Combat shows odds before the attack (Oracle of Delphi wonder reveals the actual result early).
• Resolution is a hitpoints + “strikes”/rounds system (exact round math undocumented).

Victory conditions (4)

• Domination (military — control/capitalize; Palace required), Technology/Space Race (Apollo + spaceship), Cultural (United Nations wonder; 20 culture events feed it), Economic (World Bank wonder; 20,000 gold). Exact thresholds undocumented here.

Empire management (from Info Center, not yet extracted in detail)

• City citizens are assigned as Laborers (food) / Vendors (gold) / Traders (trade-science?) / etc. — the worker-allocation model; exact yields not captured.
• Governments table is embedded in the Info Center (Despotism/Monarchy/Republic/Democracy/ Communism/Fundamentalism) — effects not yet extracted.
• Four Ages with per-civ Age bonuses (see civ table); the advancement trigger is undocumented here.

1. Exact combat win-probability for close (sub-7:1) fights — the round/hitpoint resolution.
2. City yield math: food→growth thresholds; how “trade” splits into science vs gold; production rules.
3. Governments: exact numeric effects.
4. Age-advancement trigger; city-count/population MILESTONE bonus thresholds.
5. Victory thresholds (culture-event count, domination %).
