Sci-fiRTSPvP
~137.6 hr median co-op complexity: heavy 75.8% of 417
The Squirrel's verdictBoth are persistent online space games built around grind and long-term progression rather than quick matches. Outscape trades ship-to-ship combat for 4x colonization and economy management across a shared universe, with real-time travel taking actual days. It suits players who liked Star Conflict's persistent-world structure but want empire-building instead of dogfighting.
Not for you if you want active combat over slow-ticking colonization, or dislike travel and resource waits measured in real-world hours and days.

Space Commander: War and Trade
PCMacLinux
ActionRPGBase-Building
Free ~9.5 hr median no co-op complexity: light 67.8% of 701
The Squirrel's verdictSpace Commander: War and Trade is a solo trade-and-combat game with no multiplayer. Players take on missions across a single-player economy, managing ship upgrades and cargo runs. Median playtime is 9.5 hours. Reviewers consistently flag that mission payouts fail to cover rising repair and ammo costs, and that speed control is limited.
Not for you if you want multiplayer combat, adjustable ship speed, or a mission economy where rewards keep pace with running costs.

Monetized MonetizedHeads up: leans on microtransactions or free-to-play hooks.
Free ~486 hr median no co-op complexity: heavy 67.5% of 292
The Squirrel's verdictStar Sonata 2's defining draw is its open sandbox: leveling, crafting, and a player-driven economy spread across a persistent universe where roughly 90% of content is reachable without paying. Players report 15-year playtimes, and the median sits near 486 hours, making this a years-long commitment rather than a session game. The Steam rating is Mixed, partly due to contentious dev-community relations.
Not for you if you want fast PvP matches instead of slow-building sandbox economy and long-haul progression.

SpaceSci-fi4X
$29.99 ~58.8 hr median no co-op complexity: moderate 55.3% of 2k
The Squirrel's verdictStar Conflict players who liked ship tiers and tech progression without wanting live PvP or pay-to-win grind will find StarDrive 2 offers similar ship design and empire progression in a single-player 4X. It's a one-time $29.99 purchase, no ongoing monetization, no co-op, built for turn-based empire building rather than dogfighting.
Not for you if you want live multiplayer combat, since StarDrive 2 is single-player only and reviewers report AI opponents with lopsided economic and resource advantages.

SpaceshipsMassively MultiplayerResource Management
Monetized MonetizedHeads up: leans on microtransactions or free-to-play hooks.
Free ~6.3 hr median co-op complexity: light 52.5% of 356
The Squirrel's verdictCo-op mining, salvaging, and drone management form Exocraft's core loop — a structure Star Conflict doesn't offer. It's free-to-play on PC and Mac, with no head-to-head PvP. The median playtime is 6.3 hours, and reviewers flag premium currency as the main gate on progression, with ships, drones, and cosmetics all requiring it.
Not for you if you want PvP ship combat, or premium-currency gating already wore you out elsewhere.

Massively MultiplayerMMORPGSpace Sim
~147.5 hr median co-op complexity: heavy 50.2% of 566
The Squirrel's verdictDual Universe runs on a subscription model and centers on voxel-based construction and space corporation management in a shared persistent universe. Reviewers note that unpaid subscriptions result in asset loss, and developer activity has been uncertain since 2022. Co-op is supported; median playtime is 147.5 hours. It fits players drawn to building and industry over combat.
Not for you if you want the ship combat Star Conflict offers, or a subscription model with asset-loss risk doesn't suit you.

TradingSpaceEconomy
$9.99 ~12.8 hr median no co-op complexity: light 48% of 1k
The Squirrel's verdictStar Conflict fans grinding ship tiers under a pay-to-win economy might want Cosmonautica's flat $9.99 price instead of a monetized progression ladder. You still manage a ship and crew, buy upgrades, and expand your fleet, but there's no cash shop pushing purchases. Content runs out fast: median playtime is 12.8 hours.
Not for you if you need PvP combat or multiplayer, since Cosmonautica has no co-op and reviews cite broken markets and crashes.

Uncharted Waters Origin
PC
RPGMMORPGTurn-Based Strategy
Free ~90 hr median co-op complexity: moderate 46.1% of 2k
The Squirrel's verdictUncharted Waters Origin organizes play around sailing, trading, and exploration across adventure, trade, and combat careers, with co-op supported. It's free-to-play, released 2023, with a median playtime of 90 hours. The Steam rating is Mixed at 46%, with reviewers consistently criticizing expensive cash-shop items and gacha mechanics gating meaningful progression.
Not for you if you came for ship-to-ship combat rather than trade routes and exploration, or gacha-priced progression is a dealbreaker.
