ok, took the plunge and am trying out 1.5 w/ the terrae expugnandae mod (by lusted). noticed the same problem i remembered back when i was playing w/ 1.2 last year. gaul (comfortable stalin, in this mod, at least) and spain only seem to build temples of esus and occassionally teutatis. ugh, i just don't get it. getting the AI to complete their diverse pantheons seems impossible.
