The jump mechanic currently suffers some issues with regard to high lateral/vertical velocities. I also have several arguments for tweaking the jump mechanic:

But, I think it would be a good idea that complements the other change. It is not essential that the jump mechanic be changed at all for the acceleration curve tweak to be implemented. I believe it would greatly add to immersion for many people, not just nut cases like me. It would place Evochron a quantum leap ahead of other space sims in terms of realism. It would act as a selling point for the game to replace the rather disingenuous 'no speed limit' that is currently used. Recast this limit in terms of relativity and it becomes the freedom to kiss the speed of light. This game is largely about the lack of arbitrary limits. But really it is just an arbitrary limitation. Lots of people already assume the acceleration curve is something to do with relativistic effects. The change to the acceleration curve is probably quite easy to implement since it is presumably defined explicitly by an equation in code. The change to the acceleration curve would not be that drastic and would not really affect lower speeds. I have several arguments for tweaking the acceleration curve: To be really consistent the jump mechanic should also be tweaked so the time it takes to hit light speed and jump depends on your existing velocity. If a speed limit was introduced the acceleration curve could convincingly model relativistic flight on a fun game scale level. It is not like relativity because there is no actual speed limit and the curve stops you at speeds well below the maximum you can achieve. The acceleration curve in Mercenary is a lot like something out of relativity. My primary suggestion has two parts and is quite simple.
