Video games are hard to make. Like movies and TV shows, it takes a team of incredibly passionate and skilled people working tirelessly to create them. Obviously, no game is perfect, and every game has flaws and faults of some kind. When a title ships, however, that game is supposed to be the best possible version it can be. Players may encounter a few glitches or bugs occasionally, but on the whole, the game should work as intended. Unfortunately, this is not always the case.
