yep. i think so too. i realized that throughout the game, no matter which gamespeed, youre often forced to produce a lot of wealth/culture/science (whichever applies...)
it should still be difficult for a city to specialize in all by clearing the building list so fast. or maybe lowering the hammer values. getting up to 8-12 hammers (3rd mine+rescource) in late game is damn much. and based on the commonness of crystals and stuff alike its not an exception.
some other things i'd like to add:
sandworms.
now that i startet reading the books (almost done with first one =) ) i just realized how common the worms are on arrakis. that mod doesnt match that. in most games worms stay a small side-effect devouring one or two workers from time to time rather than a huge troopmoving/tactical factor.
i would suggest adding collateral damage. also they seem to disappear atm after killing a unit. the things ive read till now suggest that those beasts dont stop till they defended their whole territory from the very last intruder. well i know that the whole sandworm thing has not been completed yet, but it would greatly increase atmosphere if they did get col.dam. and more numbers in the next patch
