Parallax Mapping is something very common in complex projects and the method has been used by experienced devs who want their game to look more unique, breaking the tradition tile mapping of RPG Maker. Of course, the pros of parallax mapping is it look good, it gives you freedom in designing your game, the cons if your image file is like 4k, it might decrease performance in lower end devices. This cons can be negated if the dev has experience in optimization, like image compression or other methods.
