^It's NCSO so, with the exception of black tiles, nothing foreign to the game would be put in. And that which was downloaded is harmless; trust me, I never downloaded anything online but it's really fine for the game.
Peeps don't enhance the game as much as you think. You sound like it's a waste of time without peeps. If I had the capacity of peeps in this park, it would have been a huge file and you'd barely get to appreciate it without massive lag. Plus my computer is from 2002 so it's a miracle I was able to produce this. It lagged without peeps.
