The realistic ceiling for Tower defense games

Two honest views of what Tower defense games do on Steam: the whole market from a systematic sample, and the games gathered here. Kept separate on purpose.

The market
A typical game sells
≈ 546–887 copies
$749–$2k after Steam's cut, est.
The top decile
≈ 21k–35k copies
$29k–$79k after Steam's cut, est.

Half the reviews in SteamSpy's sample of 2,133 Tower defense games sit with 6 of them.

Based on the 2,133 Tower defense games SteamSpy listed on August 30, 2026. It misses the games that barely sold, so these figures flatter the genre. Games are grouped by the tags players give them, which are applied loosely, so a genre's edges are fuzzy. Owners are SteamSpy estimates from review counts, not exact sales.
