Yeah no, I have seen multiple businesses closing down due to poor marketing promotion/budget.
And then we all complain that we didn't know about a certain product/service because they didn't market it good enough (we have seen it a lot of times with movies for example, then they turn into obscure classics with the pass of time, but not really profitable), also some games that didn't really made themselves known while in critical selling weeks?
Who is gonna be the brave soul to release a game when GTA VI appears? That would be marketing suicide, no matter how good your game is.
