I am fairly neutral on the matter. While I can appreciate the arguments in favor of the strategy involved in the extra layer that SE adds, I don't see it as vital to the mod. I'm just as happy making each choice fully unique in the effects it can create, instead of contributing to a pool of potentially unique effects.
Right now, I see several options:
-Leave what's there, and have someone begin the monster (presumably?) coding task of implementing SE as it is in SMAC (possibly temporary, but an easy point of reference with most effects having obvious civ counterparts)
-Create temporary/permanent civics along the lines of SMAC (Democracy, Cybernetic, etc), each with unique effects that feel sensible. (E.G. Wealth allows rushing with Gold and provides happiness for Energy Banks)
-Create temporary/permanent civics along the lines of SMAC (Democracy, Cybernetic, etc), each with generic effects along the lines of the "counterparts" mentioned in the first option, albeit without any additional bonuses. (E.G. Wealth provides +10% Credits, +10% Production, and -1 XP)
-Create temporary civics which represent the underlying categories in SE (Growth, Efficiency, etc) which only account for positives, with the understanding that it will be used as a code base for a later "full" implementation of SE (E.G. Production +1 provides +10% Production, Production +2 provides +20%, etc).
Edit: I am most in favor of the second option as a permanent solution, or the 4th option as a temporary solution.
