That is true - Nintendo knows how to make cheap products and sell it for a high price. Their games cost very little to make as they recycle concepts with the games being very samey across the generations.
Cause BotW totally plays like Skyward Sword.
And Mario Odyssey is totally just 3D land reskinned.
There are tons of games like Xenoblade.
Mario Plus Rabbids is totally like all other Mario games.
Splatoon was not in any way a new IP.
ARMs is just like every other fighting game.
In all seriousness, your argument just sound bitter toward Nintendo and negatively affects your credibility as a whole. Same for everyone that uses that tired stigma in a debate, as it shows how out of touch they are with the reality of the situation.
