Grand StrategyMilitaryEconomy
$11.99 ~31.9 hr median co-op complexity: light 88% of 3k
The Squirrel's verdictEconomy, military, and diplomacy across a full world map with AI-run nations — Dummynation covers the geopolitical sandbox loop in a much leaner package. Scope and system depth are both smaller, and reviewers note the AI repeats the same behaviors across runs. At a median of 32 hours and a Very Positive rating of 88%, it suits players who want the core nation-simulation idea without complex layered systems.
Not for you if you want SuperPower 2's depth and complexity rather than a simpler, more casual take on the nation-simulation premise.

Grand StrategySci-fiMilitary
$9.99 ~25.2 hr median co-op complexity: moderate 87.3% of 488
The Squirrel's verdictSolar Nations 2 keeps the SuperPower 2 formula: pick a nation, run its economy and diplomacy, annex or ally your way across a world map watched over by an AI. It extends the scale to Mars and the Moon and adds co-op. AI is still described as weak and systems still feel disconnected, so this suits players who want the sandbox and can tolerate rough integration between mechanics.
Not for you if you want an AI opponent that reacts intelligently or political systems interconnected rather than separate number-tracks.

Making History II: The War of the World

Grand StrategyWorld War IIHistorical
$14.99 ~102.3 hr median no co-op 79.7% of 399
The Squirrel's verdictSame nation-management core as SuperPower 2: economy, military, and political stability sim where you steer any country through diplomacy or conquest. Making History II narrows the scope to WWII alternate history rather than modern global sim, with a steeper learning curve but more structured campaign focus. Good fit for players who want the same country-management loop with historical grounding.
Not for you if you want the freeform modern-day sandbox and open-ended global scope rather than a WWII-specific alternate history setting.

Closest Match Closest MatchThe most similar game to the anchor, by what players say.
Grand StrategyTacticalMilitary
$19.99 ~199.8 hr median no co-op 76.9% of 1k
The Squirrel's verdictSame pitch as SuperPower 2: pick any nation, run its full economy and military, wage war on your own terms. Supreme Ruler Ultimate goes deeper on unit-level combat, with thousands of individual units instead of abstracted forces, and runs continuously from 1936 into the future. Steam rating sits at Mostly Positive, with reviewers logging 200+ hours median.
Not for you if you found SuperPower 2's systems complex enough already — reviewers describe this one's UI and war management as harder to control, not easier.

Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$9.99 ~111.1 hr median no co-op complexity: heavy 77.7% of 251
The Squirrel's verdictDeeper production chains and unit-level military control are the main draws for grand strategy players who want more granular management than SuperPower 2 offered. Supreme Ruler 2020 Gold runs any nation across campaign, sandbox, and scenario modes, but reviewers note that AI naval passivity causes wars to stall for decades once island nations are involved, and the game can become one-sided early.
Not for you if you want naval warfare that resolves cleanly, or an AI that remains competitive past the early game.

Rogue State Revolution

Turn-Based StrategyGrand StrategyPolitical
$12.99 ~17.7 hr median no co-op complexity: moderate 76.3% of 539
The Squirrel's verdictBoth let you run a nation's economy and politics against reactive world powers, but RSR narrows the scope to a single country with domestic approval ratings, welfare/tax tradeoffs, and coup threats instead of SuperPower 2's whole-world simulation. Good fit if you liked managing one economy more than juggling global AI diplomacy, and want something built for 64-bit systems.
Not for you if you want SuperPower 2's global scale with dozens of playable countries and full-world military strategy rather than one nation's internal politics.

Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$29.99 ~79.1 hr median no co-op complexity: heavy 75.6% of 454
The Squirrel's verdictSame nation-management scope: control any country's economy, military, and diplomacy on a world map divided into regions, with an editor for modding. Making History narrows the sandbox to World War One instead of open-ended global play, and reviewers report AI and balance issues favoring Allied units over Central Powers equivalents.
Not for you if you want SuperPower 2's any-era, any-scenario freedom rather than a fixed WWI setting with historically unbalanced unit stats.
