Pizza Tower: Catholic priests bless Peppino's transformations away. In one of the final levels, they are exorcists who give him an angry cross that floats around him for a bit, enabling him to kill previously-invincible ghosts.

AntonBlast: the main antagonist is literally Satan.

Conclusion: Wario Land is a positive influence for Christianity. The reason Nintendo killed the franchise might be because known stockholder JP Morgan Chase Bank, acting on behalf of anti-Western interests, purchased enough Nintendo stocks that allowed them to force the company to stop making new Wario Land games, giving them the WarioWare route instead to keep the public distracted and unaware.

It is highly likely that a new Wario Land would cause a butterfly effect that results in a unified Europe retaking Constantinople and the Holy Land, expelling the Turks back into Central Asia and the jews into the desert.

It is entirely possible that Wario fans so hardcore they are making their own Wario-likes have received this revelation and, consciously or unconsciously, are acting as agents to pave the way for Wario Land's return.

The future of Christian Europe may depend on Nintendo making Wario Land 5.
