A intergalactic gangsta power fantasy set in a virtual world is not necessarily the sort of game where I particularly expected to find well developed and sympathetic characters, but thats what Saints Row 4 is and that's exactly what you will find.
I found SR4 was a game that respected my time like few others, it's willingness to build upon what went before while exploiting and playing with my expectations about gameplay mechanics and character archetypes means barely a moment is wasted. Instead what you do, and those you do it with is put firmly in the spotlight. Its near fanatical the old adage of “show, don't tell”.
For me the easiest way to explain why it's worth looking past Saints Row's surface and paying attention to how smart some of it's design decisions are is to look at its relationship with music. While the GTA series was certainly the first to pioneer the idea of in game radio stations SR4's 'thing' has always been that music isn't just something you hear as a player but part of the world that the characters also have a relationship with.
