# Hmmsim vs City Train Driver Game 2020

The clearest difference is rating: City Train Driver Game 2020 at 4.5 against Hmmsim's 3.7. City Train Driver Game 2020 also leads on update cadence (every 2 months vs every 5 months) and ratings volume (1.2K vs 170). Hmmsim's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. City Train Driver Game 2020 sells 10 one-off in-app purchases. Hmmsim asks for nothing beyond the download.

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.

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.
