The winners: Winners here lead with Dwarf + Co-op, priced around $30.
The era: Only 2 of your 8 similar games shipped in the last two years. 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).
