So just a question. Do you think that the rule was followed in Civ 5? 33% Old 33% Improvements of old 33% New stuff I think there is more new stuff then old or improved. HEX, CS, 1UPT and numerous more examples. Improvements to me would be the way some terrain looks, like farms (not rivers!). Also the way the borders move. Old would be of course certain things we remember and love/hate. There are of course many regressions in Civ 5. The tech tree got hit by lightning, the trade routes were all looted and towns were abolished. It is interesting to look back at the rest of the series. Did they follow his Rule of 33s? I actually think they did. Most of the other series had a continual improvement and most of the improvements kept passing along to the next series. Ok, would just like to hear your thoughts on this.
