Design risks
| R1 | Compulsion-loop pressure | 0.00 | |
| R2 | Monetization | 0.08 | |
| R3 | Social risk | 0.00 | |
While OpenTTD is largely free from manipulative design, the presence of microtransactions, even if minimal, introduces a slight monetization risk. The open-ended nature of the game, while beneficial for engagement, could lead to extended play sessions if not managed.

Regulatory design checks · DSA — Assessed: meets criteria·GDPR-K — Assessed: meets criteria·ODDS — Assessed: meets criteria
- DSA:What Ludograph checks: whether the game's design gives minors the transparency the EU Digital Services Act expects: plain terms, honest defaults, and clear reporting routes.: Estimated from review data. No dark pattern or child-targeting concerns found.
- GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.: Estimated from review data. No privacy or child-targeting concerns found.
- ODDS:What Ludograph checks: whether paid random-reward drop rates are disclosed, as required in China, Japan and South Korea.: Estimated from review data. No paid random-reward mechanics found, so drop-rate disclosure requirements do not apply.
These reflect Ludograph's assessment of the game's design practices against each framework's criteria, not a legal compliance determination.
