This is probably the hardest one to rank, considering that all GBs are at least somewhat good on Level 10.

Normal-Level Effciency (NLE) - How the Great Buidling benefit you on Level 10.

Spacial Efficiency (SE) - How the bonuses justify it's space usage, relative to the age.

Obiviously 10/10 is for the Great Buildings that basically never loses their value, while 0/10 is for the GBs that literally loses like 99% every age.

Depreciation Rate (DR) - How quickly will the Great Building lose its value due to inflation or depreciation of their value.

If a Great Building does not have a PAP, this is omitted and the PAP will not be counted as a category. Again, this is looking at the bonus and the amount, relative to the size and amount when you'll probably build it.

Passive Praticality (PAP) - How useful the Great Building's passive bonus(es) are.

If a Great Building does not have a PRP, this is omitted and the PRP will not be counted as a category. This is looking at the bonus and the amount, relative to the size and amount when you'll probably build it.

Production Praticality (PRP) - How useful the Great Building's production bonus(es) are.

Lighthouse of Alexandria (37.1%, AA: 185%)

Oracle of Delphi (43.6%, Active Adjusted (AA): 205%)
