The middle of these games

≈ 365k–445k copies

≈ $1.2M–$2.3M after Steam's cut

from ~9k reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

No genre covers most of your similar games. The closest is Base-Building (2 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: UNO at ≈ 1.9M–3.0M copies, ≈ $5.1M–$13.8M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering
Your set
Your set clusters on Base-Building (2 of 8) and Shooter (2 of 8).
The winners
Winners here lead with Card Game + Tabletop, priced around $10. The breakout hits carry Card Game + Tabletop + Board Game; a typical game here doesn't.
The era
None of the games you compared shipped in the last two years; the newest is from 2018. That says more about your picks than about the market, so add newer similar games to read the timing.
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 38 for the most recent game here to about 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
