One if the issues with Traveller's technology system is the lack of efficiency and progression. As an example, Vacc suits in Traveller rarely get lighter, less expensive, or add additional features. This true of pretty much all components, equipment, and weapons. There is no systematic way to reduce cost, weight, or manufacturing time. There is no benefit to additional capabilities and if there are they are always more expensive.
I do recall in the old days a supplement or article that discussed technological progression of vacc suits, and that may have been DGP. There was even a modular build system for custom vacc suits in CT JTAS.
Should components and equipment get lighter, cost less, or add capabilities. Not just vacc suits as an example, but all technology?
Just one man's opinion, but I thought it would be a neat discussion.
Best regards.
