Not necessarily the best way, but just a different way to play. Sometimes to get certain items in a game it takes a lot of time and hard work. With the use of cheats/hacks/glitches etc. you can get them much faster. Sometimes games get annoying with the backtracking and what not. Some games also have glitches that allow you to bypass these parts. So it's not necessarily something that harms your experience. I remember in an NFS game, we once used codes to use different types of vehicles, like the school bus, T-Rex and other stuff.
