2 of your 8 similar games are hits.

No genre covers most of your similar games. The closest is 4X (4 of 8), so the genre you lead with is still undecided.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: RimWorld at ≈ 7.5M–12.1M copies, ≈ $71.8M–$193.1M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 22 reviews in their first month; the spread ran 3 to 352.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on 4X (4 of 8) and Tactical RPG (4 of 8).
The winners: Winners here lead with Colony Sim + Base-Building, priced around $35. The breakout hits carry Survival + Building + Simulation; a typical game here doesn't.
The era: The games you compared span 2016 to 2025, and 1 of your 8 shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
