What drives the score

How to read this

Grades run S to D, read from the buyer's side. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. How the grades work

What we assumed
  • How long it takes to beat isn't in our data. We scored it as a typical Strategy game (about 8 hours) and docked the score for the missing length.

The value story

The lowest price on record is $1.99, set in December 2025. 59 discounts in the 6 years on record. They run about 75 percent off, roughly 6 weeks apart.

Against its own genre it lands in the top 28 percent on value. It is pricier than 90 percent of its genre, and better reviewed than 84 percent. Among the games that feel like it, House Flipper 2 ($39.99, scores 55) beats it on value, while it beats Desynced ($29.99, scores 35).

This site sampled 461 of its Steam-purchase reviews; 6 were written by buyers who refunded it, sampled from reviews written June 2020 to September 2026. Inside the two-hour refund window, 65 percent of the 121 reviews written there were positive, against 83 percent overall, and those are 12 percent of everything written about it.
