it took me a little over 5 months to get my last collectible..and i play this game every day for several hours looking for them i think i got cheated though...my population limit is 115 and it was 105 before i got the last one and i got +5 for that (110) then i got a seperat thing like 5 seconds later telling me i got +10 (120??) but I can only go to 115 ..beats me
