I don’t know about other peoples’ experience, but settled great people are kind of underpowered (barring special buildings or synergies). Can a settled great person also give gpp?
really the settlement of Great People is very weak. does not pay off when compared to the unique building they give (especially the Academy, manufacturing).
One way to make it stronger would be to actually give GPP for these grat settled units. However, in order not to be an exploit, we could do it in a staggered way with regard to the buildings present in the city and the type of great people, as if it were due to the influence of a legacy left by this great unit. Example, a settled Great scientist would give +1Great Scientist Point per turn in that city if it has a university, +2 if the city has a university and observatory, +3 if the city has a university, observatory, laboratory, and +4 if the city has university, observatory, laboratory, supercomputer.
So the bonus would be scaled throughout the game, not concentrated, which would be an exploit, if it were like a citizen working as a scientist that gives the +3 GPP (plus the percentage increases for buildings).
To prevent these settled great people from being too strong for a very long time, one idea would be to skip the first building in the chain, so that way the GPP points would only be accumulated when the tech that unlocks a certain building is discovered and that building is built in this city, this would already serve to delay the start of obtaining these GPP points, which would not unbalance the game too much as it would postpone the bonuses to a more advanced stage of the game.
Settled Scientist - library(+0), university(+1), observatory(+1), lab (+1), supercomputer(+1).
Settled Merchant - market (+0), bank (+1), Warehouse (+1), department store (+1)
Settled Engineer - Forge(+0), Factory (+1), Industrial Plant (+1), Automated Manufacturing(+1)
