I agree with Sigtrygg
Our society has become accustomed to instantaneous communications. This is very natural for humans, it allows for control and understanding. Every child clamors for 'now'. Every parent is happy they can reach out to their child anywhere, anytime.
We spent a lot of time and resources getting to that stage.
Its not something we want to willingly give up.
Most video and board games give us an omniscient view of the game. We control fleets in real time on opposite sides of the galaxy, with full knowledge of what is happening to each fleet. We control multiple individuals, and choose their reactions with full knowledge of what we are going to choose for the other one. Cheats that turn off fog of war are some of the most popular cheats in video games.
The time lag that jump rules force upon a Traveller goes against all that we've worked for, and grown accustomed to. Its not popular, for very good reason.
If we want it to be accurate, its going to be uncomfortable, and unpleasant. By definition. Trying to make it comfortable, or smooth, is literally going against the point of the jump rules. It would definitely be more popular, but it wouldnt be accurate.
Given that, i fail to see how we could have a set of rules that doesnt feel uncomfortable and annoying, without giving up one of the core assumptions of the setting.
