so far i've only see 3 epic tokens for highest buildings. so i think thats max. i did first to projects but im reluctant to start 3rd because it suggest mountain buildings which i have very few,
the more speciality buildings you have for that project the more chances to finish more tasks you have, because while you might get stuck having to build 5 yogurts or some other hard item, you can keep doing easier tasks. tasks pop up again on the same building after a little while.
so far i havent managed to get to 160 on any project, but im happy with 2 silver buildings. 🙂
its an interesting concept, gives you something to do , after you have updated all buildings to skyscrapers while keys are hard to obtain due to lack of WU items,
it could have been better documented so people dont jump and start epics right away, only then city is capable of sustaining the high task request. i agree that 24h timer is too little. other then that i dont have complains.
