If that's true, then I stand corrected. Though it might be just temporal fluctuation in the game trends. If lots of people wanted the type of shooter where maps, missions, and gameplay are designed appropriately for looser weapon handling, then there eventually should be enough games like that, according to the laws of supply and demand. Game makers naturally want to try different things and I don't think they are immune to following (copying) general trends in the business either. Though there have always been more games than game engines, and if some popular engine supports better one type of gameplay, then the designers likely stick to it.
