Well the way I imagine it and I realized that I have in no way mentioned it but I felt it was kind of like that show, Cowboy Bebop. You know where the setting is futuristic there are futuristic technology available but the items used are still recognizable. Such as a pistol will still look like a pistol of today but hey if it shoots bullets or lasers that is up to the user. Their just has to be a trade off like lasers eat through almost anything but is susceptible to overheating problems and where are bullets would be weaker in this scenario, the rounds and rate of fire would be superior to that of a laser pistol. So really, futuristic but not too futuristic. This is human civilization collapsing and innovation really slowed down, intergalactic space travel and colonization of other planets wasn't achieved, things of that nature.
