It would be good if one stayed in level 25 as there are lesser time consuming items to manufacture and also most of the specializations are unlocked provided you do not want landmark specialization buidings.
Out of interest how many buildings with 3 epic points do people have? I currently focused all my attention on education and have no specialization buildings of any of type. I currently have four Universties and am working towards my fifth.
im also interested to know what type of items people are creating and hoarding prior to starting a challenge. I guess a lot of this will be dependant on your max storage which S why I'm currently spending all my free gold on upgrading this as quickly as possible.
