I threw some commits together for this to get a general feel for it.MatGB @ http://www.freeorion.org/forum/viewtopic.php?f=28&t=10534#p88512 wrote:My current plan is to simply double all the existing parts, I'd like to simplify ship speeds so they're always a multiple of 20 but that's a lower priority. If they're all doubled then the max speed is 200, and I'm fine with that. 20, 40, 60, 80 are nice simple stat bonuses.
A few differences from just doubled stats and limiting to one per ship.
Improved(internal): +20 speed cost/time:15/3 (from 10/3)
Dimensional(internal/core): +40 speed cost/time:25/5 (from 20/4)
Transpatial(core): +60 speed (+40 stealth) cost/time:80/8 (unchanged)
Singularity(core): +80 speed cost/time:40/6 (from 30/5)
No changes in techs (but need to update descriptions).
Dimensional drive gains ability to mount in core slot. Gives some access to using core slot earlier in game (e.g. gravitational hull).
If this portion gains acceptance, will need a distinct icon for internal+core type parts.
Singularity Engine Core outperforms Transpatial Drive for raw speed. Might need some flavor text adjustment.
Singularity is the end goal of the speed tech line, where Transpatial is a side-effect within the robotic hull line.
Cost was not changed as it potentially saves a slot for engine + stealth.
Costs were increased starting at 15 (more than most fuel parts, cheaper than shields) and slightly less than double cost for doubled speed.
Added 1 turn to Dimensional build time due to core slot addition.
Added 1 turn to Singularity build time due to Dimensional and top speed status.
Expect costs may want adjustment and some other changes were not discussed previously.
