They must have been talking about linearly separable hypercubes. Euclidean Civilization confirmed.
Well, considering the Fourth Dimension is sometimes regarded as time, it could fit well with the "Moving your city" concept some are thinking...
Ummm, you're slightly misinformed
Receives +3 Gold and +1 Culture for each International Trade Route with a different civ or City-State. The Trade Route owners receive +2 Gold for each Trade Route sent to Morocco.
Possibilities that are outside the box in comparison to normal gameplay
Venice - with some sort of land reclamation ability or Buying CS's (no settlers at all).
The City States - you pick one and start with no added abilities at all. Possibly no settler option.
A camp only civ - you only have 1 square around each camp rather than 3 (that could fit native american with small tribal camps rather than big cities or even Inuit)
A Barbarian civ you cant found cities you can only capture them. Start with a camp (see above)
A customisable civ - You pick the abilities from a list of provided options. If this was planned to be the last expansion initially then that might make sense.
A one city only civ - Something like Troy.
I've thought it would cool if there was an "anti-Austria": someone who could turn their own cities into allied city-states.
If you settle on another continent and the population reaches 6 or something like that you have an option to form a new city-state.
As Venice you play as Enrico Dandolo:
Spoiler :
And of course you get a bonus when you sack Constantinople
Tibet sadly can't ever be a civ, no matter how great it would be
Maybe they retooled the "very cool"/"great new" (Ed's words) Pueblo mountain UA for another civ - like Tibet!
(Yes I'm aware of the "no Tibet because it'll piss of the Chinese government" argument, but I don't think it holds as much water as a that.)
not sure whether this was mentioned before.
"hypercube" is a canadian movie.
edit: nvm, it was.
