My ideal Civ6 would include, but not necessarily be limited to, the following features:
-Ctp2 combat system combined with SMAC artillery bombardment system
-Self-founding religions which are founded in any city at random once an appropriate enabling technology has been discovered
-Realistic corporations mechanic similar to the one in ROM-AND
-Stability /revolutions mechanic based on the systems in RFC and LOR
-Public works system like in CTP, with the Worker unit abolished
-Optional future era which can be enabled or disabled at the start of the game by the player
-Resource limits for some units
-Depleting resources based on usage, new food resources appearing on farmed tiles
-Depleting of rivers and lakes due to excessive irrigation
-Plague mechanic similar to RFC
-Enhanced options and more benefits for small empires e.g. happiness bonus for having only a few cities (but NOT a happiness penalty for having many cities), can only build some powerful
national wonders if you have a small number of cities (with those national wonders losing effect if you acquire too many cities later in the game), or smaller number of cities with a certain
improvement (e.g. university) needed to build a national wonder (e.g. Oxford University)
-Climate/pollution mechanic based loosely on SMAC's pollution and weather system, combined with something like the Armageddon Counter from FFH i.e. environmental destruction/terrain change
becomes more frequent and intense as the counter rises and less so as the counter falls
-Blind research option similar to SMAC
-Tech diffusion along trade routes
-Probability-based mechanic for technological progress: rather than generating beakers per turn to acquire a tech which costs a certain number of beakers, you work to optimise the conditions
for technological progress in your civ, thereby improving the *likelihood* of technological breakthroughs occuring on any given turn (this can be done by direct science funding as well as other
means)
-Environmentally conditioned research, e.g. can't research horesback riding without access to horses, can't research sailing without access to a coastline (but can still acquire these techs from
other civs)
-Chance for barbarian cities to become full-fledged civilisations
-Self-founding cities (in addition to settler-founded cities) which can spontaneously arise at important places on their own e.g. at river mouths, on forts, or on roads between other cities. This
mechanic essentially already exists in Civ4 but is confined to barbarians
-Natural wonders which confer benefits to civs that control them, similar to the special terrain features in SMAC
-Ability to claim land prior to settlement, and dispute land claims of other civs
-Tourist revenue from certain World Wonders which have been around for a long time, like in C3C
-Adaptive civ traits which arise and change through the course of a game based on a civ's playing style: e.g. build near the coast and build a lot of naval units and you might eventually acquire a Maritime trait which improves ship strength and sea commerce; fight a lot of wars and build alot of military units and you may acquire a Militaristic trait which improves combat strength and increases the rate of barracks production and unit promotions)
-Civ traits affecting the speed/likelihood of discovering certain techs e.g. Maritime civs better at researching seafaring techs like Astronomy
-Food transfers between cities, as was possible with food caravans in Civ2
My ideal civ6 would, at the very least, do away with:
-1 upt
-Global happiness
-Spiffy but boring and resource-hungry CGI World Wonder videos
-Spiffy but unecessary, resource-hungry and (ultimately) annoying CGI animated leaderheads
-Diplomatic penalties and bonuses which are over the top and last for all time (e.g. having a -4 "You traded with our enemy" from Tokugawa for that tech trade I did with Catherine 3000 years ago)
-Redding-out of options at the bargaining table! This feature annoys me no end - everything has a price, it's just that sometimes that price is so exceptionally high that it's well beyond the realm of affordability. So be it. I would rather be told "you can't afford this" than "you will never get this no matter what".
-Mountains being impassable and useless
