Well, this will suck for those who don't use euros as their coin, but DrillLand has a price of 20€ instead of 30$. I don't know if Katamari Damacy ReRoll also had a 30$ launch price, but in Europe we got both games at 20€.
Why Bandai Namco charges less money on the european region is beyond my understanding, but it has to suck for american players, considering we can get DrillLand for roughly 11$ less and Bandai Namco games that aren't Dragon Ball themed tending to perform decently at best in Europe.
