I think he's asking if possible in a game to build XX houses to reach 1000 pop limit. I think if you covert all the ma with houses you can reach 1000 pop limit....
Well it would take 200 houses (not counting TCS) and they take 4 tiles each meaning you would need a total of 800 tiles. On the map size tiny there are 120x120 tiles, which is a total of 14400 tiles meaning you could easily do it
I'm not talking about space, I mean how to make that houses will be required (with triggers)? On the 1000 pop maps I've played you don't need houses at all and your pop limit is 1000.
1000 population limit but houses are required
This has triggers for population.
