My OCD issues dealing with ship storage stems from my last case. It was good, for a while, but then I out grew it. I do not want to out grow another case system.
So my criteria for a set up would need to reduce the risk of...
1) running out of space.
when you fill a box you just clamp on another box
2) too small to fit every size ship.
these cases should have no issue carrying Capital Ships
3) leaving stuff behind.
I hate getting somewhere and realizing that I have forgotten something
I know I do not need to have all my ships in the same case or with me always. But if I have everything in one location, in a case that I can carry in one hand this makes me feel better. These are not perfect cases but they help ease the anxiety for forgetting something or the trauma of running out of room.
