While the game excels in cognitive benefits, its WWII setting involves a high level of violence inherent to combat. The narrative also carries a notable level of propaganda, framing the conflict with a clear good vs. evil dichotomy. However, it exhibits very low risks concerning compulsion-loop design, monetization, and social interaction, making it a relatively safe choice in these areas.
