ReceptionRating · Positive reviews · Number of ratings

City Train Driver Game 2020 holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: City Train Driver Game 2020 has 1.2K ratings behind it against 170, so its average is the more settled of the two. Written reviews complicate that: 70% of Hmmsim's written reviews are positive against 62% of City Train Driver Game 2020's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hmmsim ships an update every 5 months, City Train Driver Game 2020 every 2 months. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
