Grand StrategyMilitaryEconomy
$11.99 ~31.9 hr median co-op complexity: light 88% of 3k
The Squirrel's verdictSame premise: manage a nation's economy, military, and diplomacy while an AI runs every other country on the map. Dummynation is smaller in scope and simpler in systems, but it's actively maintained, with recent updates changing alliance and invasion mechanics. Suits players who want the geopolitical sandbox loop without SuperPower 2's technical baggage.
Not for you if you want SuperPower 2's depth and complexity rather than a leaner, more casual take on the same nation-simulation idea.

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.

ModernTacticalWargame
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 verdictSame pitch as SuperPower 2: run any nation, manage economy and military, watch an AI-driven world react. Supreme Ruler adds deeper production chains and unit-level military control, at the cost of similar AI weaknesses, including passive naval forces that stall wars for decades. For players who want more granular management under the same open-nation sandbox premise.
Not for you if you want fixed AI aggression problems rather than a deeper economic layer bolted onto similar diplomatic and military shortcomings.

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.

Power & Revolution 2022 Edition
PCMac
Grand Strategy4XPolitical Sim
$49.99 ~96.9 hr median no co-op complexity: heavy 59.4% of 965
The Squirrel's verdictSame core loop as SuperPower 2: run a country's economy, diplomacy, and military while an AI simulates every other nation. Power & Revolution carries over the geopolitical sandbox scale but reviewers report persistent bugs, disappearing data, and yearly editions that reuse prior content. Fits players who want the spreadsheet-and-map simulation depth regardless of AI or stability complaints.
Not for you if you want fewer bugs than SuperPower 2 had, since reviewers describe recurring crashes, disappearing characters, and inflation glitches carried across editions.

Masters of the World - Geopolitical Simulator 3
PCMac
Political SimPoliticsPolitical
$34.99 ~41.7 hr median no co-op complexity: heavy 45.6% of 612
The Squirrel's verdictSame pitch as SuperPower 2: run a nation top-down, tune economy and diplomacy, watch neighbors react. This one goes deeper on granular policy (speed limits, school age, blood toxicity laws) and detailed legal systems, but reviewers report game-breaking bugs, crashes, and AI war logic as shaky as SuperPower 2's, with less consensus that it's worth the price.
Not for you if you want stability over depth — reviewers cite crashes, save-breaking bugs, and inconsistent deficit/surplus tracking that can end a playthrough.

Realpolitiks 3: Earth and Beyond
PCMacLinux
Grand StrategyPoliticalEconomy
$24.99 ~8.9 hr median no co-op complexity: moderate 38.2% of 296
The Squirrel's verdictBoth let you run a country's economy and diplomacy while an AI drives every other nation, and both games' AI struggles with coherent behavior. Realpolitiks 3 adds AI-generated leader portraits and dialogue, which reviewers describe as inconsistent and sometimes absurd. Released in 2025 and still drawing frequent updates, it suits players wanting the same sandbox with modern visuals over stability.
Not for you if you want a finished, bug-free simulation rather than an actively patched Early Access title with reported broken political and economic logic.
