If you spend marketing money on the PC version and then it gets pirated a lot, that's a bad roi for the game developer. Also, supporting PC well is expensive because the hardware varies so much. As a result, Steam reviews suffer. If Nintendo spends money to promote your game because they know piracy isn't an issue on their platform, that's always a huge win for the developer. And support is much easier because everyone has the same standardized hardware. So the developer even gets a better profit margin out of each sale. That's the gist of why many games start out as a time limited console-only release and then later expand to PC when the engine matures.
