Why have game designers strayed away from virtual reality games?

the simple answer is that there is more money in games such as FPS's more people play them, there is less they have to worry about so the production is quicker. its easier to make them look prettier so theres another selling point. less ideas are needed to be put into the game. were as virtual reality games. they need a geniune idea to get the game to shift. consoles took over aswell, if a company made a game purely for pc, they would loose a large margine of custome. its alot harder to make a virtual game for console due to the lack of keys for controlls.
